Martin AC（マーティンAC） アラミドカーボンアウター仕様のラケットです。最新のラインアップで、まだWRMで取り扱いはありませんが、今後WRMで取り扱い販売されるのでしょうか？。アウターカーボン、板厚5.8 mm、上板リンバのラケットになります。非常にスタンダードなブレードの厚さですが上板Limba（リンバ）なので、張継科ALCや林高遠ALCよりも柔らかくて球持ちを感じるはずです。打球感が近そうなラケットはフレイタスALCになりますが、フレイタスALCはブレード厚さが6.0 mで、マーティンACの方が薄いので飛距離も抑えられておさまりが良いと思います。水谷隼ZLCシリーズも上板がリンバなので、打球感は似ているかもしれません。
Martin Pro（マーティンプロ） 7枚合板なのに珍しい板厚6.0 mm、上板リンバのラケットです。上板リンバは、例えばミズノのフォルティウスFTが挙げられるますが、板厚6.0 mmはフォルティウスFT Reの6.1 mmよりも薄いですね。7枚合板の力強さと、飛距離が抑えられたラケットではないかと想像します。
Vario AC＋（ヴァリオAC+） 最新のOSPラケットで、片面は上板コト材にアラミドカーボンアウター、もう片面は上板リンバにインナーアラミドカーボンという、男心をくすぐる一本ですね。片方は攻撃的に、もう片方は球持ちを重視するという構成になっています。合板構成も芯材から非対称となるラケットはあまり一般的ではなく中途半端になりやすいと言われますが、一般層でフォアもバックも同じレベルでスイングできるレベルの人は少ないわけで、こういったラケットの需要は少なからずあるのではないかと想像します。自分が持っているラケットではPro-13Sという中国製のラケットが近いと思いますが染色剤を上板に使用していてやや硬めのイメージです。OSP製のVario AC+の方が球持ちを抜群に感じられるのではないかと想像します。
正直、アルネイドのインナーバージョンということで、試打するまでは上板にコト材を使っているのではないかと思って購入しました。実際の試打では、全くコト材の硬さを感じなかったので、おそらく上板はリンバではないかと思います。上板にコト材を使っているラケットはニッタクさんのTornado King Power（トルネードキングパワー）になります。このトルネードキングパワーと比較するとアルネイドインナーは明らかに打球感が柔らかく安心感があったのでリンバだと確信してしまいました。 トルネードキングパワーはインナーラケットであるにもかかわらず、アウターカーボンラケットのようなキレと威力のボールが打てる非常に優秀なラケットですね。上板にコトをもちいていて、打球感もかなり硬く、回転性能の高いラバーや粘着ラバーと相性がバツグンです。一方で最近のスピン系テンションラバーを使いこなすのはやや難しいとも感じました。廃盤ですが、まだ手に入るかもしれませんので、気になる方は是非検討してみてください。

Review Rakza Z Extra Hard. This rubber is YASAKA’s high-end rubber for a long time, and it will be an adhesive tension rubber! At the timing when Butterfly released the latest adhesive tension rubber, Dignics 09C, in 2020, this Rakza Z was released so that Yasaka would also chase after it. There are two types of hardness, Rakza Z, which is about 50 °, and Rakza Z extra hard, which is one or two of the hardest rubbers in Yasaka. This page reviews Rakza Z Extra Hard. The user of this rubber will be Fumiya Igarashi, who joined TT Saitama after graduating from Waseda University, and recently Takuya Jin, a signboard player of Yasaka. It seems that You Tuber and Goblin’s Yanma are also using it.
Speaking of Yasaka’s contract players, Takuya Kami, who won second place in the All Japan Championship in 2014, Mattias Falck (Sweden), who won second place in the 2019 World Championship, and Ma Lin, who won the World Cup four times as an advisor and won the Athens Olympics. (Marin, China) The players are famous. There are also many contract players from Waseda University, including Fumiya Igarashi, who won the Kanto Student Championship, Asuka Sasao, who won the Junior Division of the All Japan Championship, and Yuko Kato, who won the second place in the Kanto Student Championship. In addition, there are many sharp contract players with Aida Satoshi who is active until TT Saitama with a different back cut man. God is a player who continues to use Rakza 7, Rakza X, Rising Dragon (Shoryu), Rakza Z extra hard and Yasaka’s high-end rubber in order, including when he was a student. Not only top players but also amateur players use Rakza 7, Rakza X, and Shoryu, and I think they are very famous rubbers. Rakza Z is likely to spread in no time.
The Rakza series is a very proven series, and in the olden days, the god player mentioned earlier used Rakza 7 when he won the All Japan Student Championship and Rakza X when he won the All Japan Championship runner-up. Also, in recent years, Meiji University’s Tezuka Kouma, who is a heterogeneous player who makes heavy use of smash, used Rakuza X when he won the championship, and Yoshiyama Ryoichi of Aiko Daimeiden used Rakza X and Rakza 7 when he won the 2022 All Japan Junior Championship. I am. It is not a minor rubber, but a rubber series that even top players can get enough results!
Rakza series
The Rakza series is YASAKA’s signature tension rubber series. All Rakza rubbers are Hybrid Energy type rubbers, which are “combined with the high grip and spin performance of high elasticity and high friction rubber, the high repulsion of tension rubber and the refreshing shot feeling”.
Similar to Butterfly’s Tenergy and Dignics series, the image of the hitting trajectory is posted on the YASAKA homepage and pamphlets. The rubber with the highest arc is the Rakza Z, which was sold in the spring of 2020. This is followed by Rakza X, Rakza 7 and Rakza 9. I think you can think of it as follows when it is compatible with the Dignics series. Rakza Z ⇄ Dignics 09C Rakza X ⇄ Dignics 05 Rakza 7 ⇄ Dignics 80 Rakza 9 ⇄ Dignics 64 The Rakza Z, which will be released in the spring of 2020, is an adhesive rubber, and it will be in the same classification as the Dignics 09C released at the same timing. Is this a coincidence, isn’t it?
If you explain the Rakza series in detail, there are four types of Rakza rubber, each of which is different in detail. There are two types of Rakza Z, Rakza Z and Rakza Z Extra Hard. Rakza X uses Non Slip Sheet (NSS) technology and is said to have a high grip that sets it apart from other Rakza. In terms of performance values, the amount of rotation is higher for Rakza 7 next to Rakza Z. And the fastest in the series is Rakza 9. Soft sponge is sold in two types, Rakza X and Rakza 7. The rubber series, which is very popular even though it has different parts in such small parts, is the Rakza series. The Rakza Z EH to be reviewed this time is a Dignics 09C type rubber among the butterfly rubbers, so I would like to confirm the performance of the Rakza Z EH as an adhesive tension rubber.
Performance of Rakza Z Extra Hard
Coincidentally, when the performance values are quantified and compared, the Rakza Z EH is in the same position as the Rakza 7 software. Of course, reflecting the hardness, it can be said that Rakza Z EH is the rubber with the highest spin value. On the other hand, although it is faster than Shoryu, you can see that Rakza Z EH is faster than Rakza 7 and Rakza X. This area can be said to be a characteristic of adhesive rubber.
The Rakza Z Extra Hard is quite heavy, but the hardness is as hard as Tenergy 05 (from the result of the shore c sheet). However, YASAKA’s rubber does not have a good hardness, so it is Rakza Z Extra Hard that feels as hard as Dignics 09C. Also, the characteristic is the difference between the seat side and the sponge side of shore a. In short, you can see that the seat side is softer and the sponge side is harder is Rakza Z. It seems that the theory is that the seat side of rubber called Dignics 09C and spin type tension rubber is hard and the sponge side is soft, but the sponge is hard and the sheet is soft for Rakza Z and Chinese leopard. It may be a feature. The soft seat gives the impression that the quality of the loop drive is easy to improve, so you can expect the goodness of the loop drive from the Rakza Z Extra Hard!
Rakza Z Extra Hard Sticking and Weight
It’s a little confusing, but the Rakza Z Extra Hard sponge is a sponge with a lot of air bubbles. The amount of bubbles is like a spin tension rubber. (The black sponge is Omega VII China Ying.) Bubbles can be confirmed in Dignics 09C, but the bubbles are quite fine. Also, Hurricane is a sponge with almost no bubbles. I felt that this area was likely to appear as a difference in rubber.
The pasted racket will be Hurricane 301. It’s an inner racket. After all, the adhesive tension made in Germany bounces as a whole, so I think that inner carbon is the best if you want to taste it. Or if it’s Rakza Z Extra Hard, is it wood plywood like Yasaka’s contract player? I highly recommend the 7-plywood Ma Lin Extra Special. Also, the adhesive feeling is stronger than that of Dignics 09C and the adhesive tension rubber made in Germany. I felt that it was the same as Shoryu, or a little weaker than Rakza Z Extra Hard. While the Dignics 09C and recent German-made adhesive tension sheets do not seem to be adhesive at all, I was happy as an adhesive user to feel the strong adhesiveness of Rakza Z Extra Hard.
Rakza Z Extra Hard
"Equipped with a hard sponge for more powerful attacks"
By combining an adhesive top sheet with excellent rotational power of Rakza Z with a harder sponge, it is possible to create higher power. Even when hitting a ball with a strong impact, it accurately conveys to the ball without losing energy. It is a rubber for hard hitters that can perform power play that satisfies top players.

Features of Rakza Z Extra Hard
Good adhesiveness and good tension! And Rakza Z Extra Hard is easy to handle!
Although the weight of Rakza Z Extra Hard is heavy, I felt that it was easy to handle because it was a rubber that added the good points of adhesive rubber and the good points of spin type tension rubber! Like an adhesive rubber, the front team felt that it was easy to rotate and overwrite. I felt that overwriting push and stop could be easily made high quality, and loop drive was easy to make low rather than the amount of rotation, and I felt that this was also high quality. On the other hand, the feeling of running from the middle team was quite strong, and I did not feel the deceleration as in the adhesive rubber. It was an adhesive tension rubber that put together the good points of adhesive and spin tension rubber. Also, as a feature, there are many bubbles in the sponge and the hardness is around 55 °, so it is easier to handle than the recent 60 ° class adhesive tension rubber (Blue Grip C1 (Blue Grip C1), Omega VII China shadow, etc.). Was outstanding. I felt that the pointer of this rubber was not to compete with Chinese-made adhesive rubber such as leopard, but rather to try to get the best of adhesive rubber and tension rubber. Among them, I think that it is a rubber that makes the sponge hardness harder and makes it easier for the goodness of the adhesive rubber to come out. I think it’s a differentiated rubber in a very good way.
The sponge is hard and easy to counter drive!
The sheet is a softer rubber, but since the sponge hardness is hard in the first place, I felt that it was not easily affected by the amount of rotation of the other party. Also, although the bite is good, the flight distance is not so easy to get out, so I felt that it was very easy to counter drive. I think this rubber is a good point. It may depend on my skill, but it is Rhyzen ZGR that I felt that the counter drive fits well with the same hardness. I felt that the Rhyzen ZGR was less sticky and could be hit with an image close to spin tension, but in both cases the counter drive was a fairly easy rubber. Personally, I felt that Rakza Z Extra Hard would be better for the fore, and Rhyzen ZGR would be better for the back. I think that the counter drive fits well if Shoryu can do the same, but the Shoryu I purchased is a fairly light individual and easy to use, but I got the impression that the rubber itself seems to be defeated by the hard plastic ball. rice field. I think the Rakza Z Extra Hard is more suitable for the current plastic ball.
If you bite it firmly, you can hit a heavy drive that seems to be an adhesive rubber!
Although it will be a comparison with the Rhyzen ZGR, the Rakza Z Extra Hard was a rubber that you can feel that a very sticky ball is coming out when you hit the drive with all one’s might. I felt this part was very good. On the other hand, the Rhyzen ZGR seemed to be able to produce a ball that seems to be an adhesive rubber, but the shot feeling was similar to that of a spin-type tension rubber, so I felt that there was a strong gap between the shot feeling and the image of the ball. I feel that my tastes are different around here. In any case, I felt that I could hit a heavy drive like an adhesive rubber only after biting it quite strongly, so it is recommended to use Rakza Z Extra Hard in the foreground.
Review Each Technics
Forehand
Light hit There is no discomfort.
Drive on long balls and rallies It will bounce. I don’t think it feels strange to switch from spin tension rubber. However, it is also a heavy rubber, so you may need to be careful about that. The Hurricane 301 is also a heavy racket, but I felt it was easy to handle, so I felt the ease of handling the Rakza Z Extra Hard.
Drive with open face As with Rakza Z Extra Hard and other adhesive tension rubbers, it is better to open the surface and hit it before spinning the ball. Even if you don’t open the surface to that extent, Rakza Z can be used like a spin-type tension rubber. I think it’s a good point that the ball goes.
Top spin (loop) drive against back spin This was good. I felt that it was easy to control even if the hitting point was lowered or attracted because the bite was good. The amount of rotation may be lower by that amount.
Speed drive against back spin It was easy to do. Perhaps it was easier to get speed than other adhesive tension rubbers and I felt that it had a feeling of running.
Curve / shoot drice I felt that the way of turning was a little weak because of the speed.
Block It was easy to do. I felt that I could hold the ball because the entire rubber had a good bite.
Counter drive It was a rubber that was easy to counter. Above all, I like how it fits nicely.
Stop / push I felt it would stop firmly. It was good to be able to cut it firmly.
Serve It was a good impression that I was able to rotate it firmly. You can cut it! It’s a little easy to bounce, so I was worried about that, but once I got used to it, I felt that I could produce a well-cut serve.
Backhand
Light hit It’s a little hard.
Drive on long balls and rallies It’s not bad, but it’s a little difficult. I felt that it was difficult to reach the full potential of rubber with my own skill. Of course, since it is a rubber with a ball, it may not be impossible to handle it, but I strongly felt that I lacked skill.
Stop / push It was easy to stop. It was easy to cut. Because the sheet is sticky, I felt it was easier to cut than the Rhyzen ZGR.
Comparison with other rubbers (personal impressions)
Spin amount Dignics 09C ＞ Rakza Z Extra Hrd ＞ Tenergy 05
Speed Dignics 05 ＞ Rakza Z Extra Hard ＞ DNA Dragon Grip
Dignics 64 is the most specialized speed performance in Butterfly’s high-end rubber series, Diginics series. The target layer of Dignics 64 is the layer that uses Tenergy 64, and it seems that the intention is to propose Dignics 64 if you want more speed and rotation. The reason why katsuo000 paid attention to Dignics 64 is that Zhang Jike ZLC (Zhang Jike ZLC) and Dignics 64 were introduced on the Butterfly homepage as being compatible. The following is reprinted from the special page of Butterfly.
Also, katsuo000 is ashamed to never use Tenergy 64. I’ve used Bryce Highspeed, which is more specialized in speed, but I wondered if Tenergy 64 is a rubber similar to Blythe Highspeed, and I wasn’t even thinking about hitting it. .. I have repeatedly praised Dignics 05 as good on this blog, but I tried to use it to find out how it compares to other Dignics.
Comparison of published performance values
As you can see from the performance, Dignics 64 is a rubber with spin performance higher than Rozena and high speed performance next to Blythe High Speed. The speed performance is the second fastest among the butterfly rubbers after Bryce High Speed, so you can see that it is an overwhelmingly speed-based rubber.
Spring Sponge X and Dignics series seats
The Spring Sponge X used in the Dignics series is said to be an evolved version of the Spring Sponge used in the Tenergy series. The spring sponge is a closed-cell sponge, and it is a butterfly original technology that cannot be manufactured by other rubber manufacturers. Spring sponge X is made by making the closed cells of the spring sponge finer while maintaining independence. As a result, it seems that Spring Sponge X is 14% easier to deform than Spring Sponge, and the repulsive force is improved by 3%. Speaking of the spring sponge of the Tenergy series, the orange sponge is characteristic, but the spring sponge X of the Dignics series is characterized by the red color that can be said to be crimson, and you can tell at a glance that it is the Dignics series. By the way, sponges of similar color are from other manufacturers, and they are very similar in color to the sponge of THIBAR’s Evolution series.
It is also introduced that the surface strength and ball holding have been improved. Regarding ball holding, it is introduced that the counter and Chiquita caught on the seat are more stable. In addition, although it is strong, Mizutani also mentioned that it took longer to replace the rubber. Certainly, it takes longer for the sheet to turn white than the Tenergy series, and if the storage conditions are good, the sheet will not deteriorate for nearly a year. Considering the rubber as a whole, the tension of the spring sponge X seems to loosen, so I feel that the state changes from moment to moment. The seats of the Dignics series have a stronger transparency, but it seems that they use strong seats that are close to the cloudy seats made in Germany, so I feel that Chiquita and counters are extremely easy to do.

Three features of Dignics 64
The features of the Dignik series, the hardness of the hard sheet, the ease of stopping, and the ease of counter-driving are apparent!
The shot feeling was more similar to that of Dignics 05 and Dignics 80 than I imagined. Although the Dignics 64 is a rubber with a characteristic of speed, I felt that it was easy to firmly fix the push and the stop like other Dignics 05 and Dignics 80. At Blythe High Speed, of course, the speed was fast, and I felt that it was a rubber that was easy to rotate, but it was quite difficult to stop and stop. However, I felt that the Dignics 64 is one of the few rubbers that speeds up even though the push and stops can be stopped low. Like other Dignics, it was a very reliable rubber that could firmly fix push and Stop. In addition, the ease of counter drive, which has been acclaimed repeatedly in the Dignics series, was alive and well. It is not easily affected by the rotation of the other party. Dignics 09C may be different, but I think that Dignics 05, 80, 64 use the same sponge and the same material sheet, and the only difference is the grain shape of the sheet. Therefore, I thought that Digg 05, 80, 64, which use the same sheet material and the same sponge, have similar characteristics that appear from the sheet and sponge. I feel that the grain shape changes the shot feeling, especially the shot feeling when biting into it. Digg’s 05, 80, 64 may be quite close if the ball does not bite into the sponge. I think that the only counter drive is to bite into the sponge, but the ease of doing my counter drive seems to be whether the seat is hard or the seat is easily affected by rotation, so it is hard. I felt that the Dignics sheet, which is not easily affected by rotation, is easy to do. In other words, Dignics 64 was easy to counter drive.
The easiest to handle in the Dignics series! Hard to feel the hardness!
Although it is the content that the contract player of Butterfly is transmitted, Dignics 64 had a better bite than other Dignics. Therefore, I felt that Dignics 64 was clearly easier to handle than other Dignics. Especially meet, block and speed drive were very easy to do. In Dignics 05, the ball often falls due to insufficient impact, and you may make a mistake due to the hardness of the rubber before holding the ball. katsuo000 is conscious of the trunk to make up for the difficulty of Dignics 05, and is conscious of shaking by the rotation of the waist instead of shaking only by hand, but the fore and back are turned back by that amount. It’s easy to be late, but with Dignics 64, I could use it without worrying about it.
The fastest ball separation and fastest pitch in Dignics!
Dignics 09C is an adhesive rubber, and Dignics 05 is also a rubber that makes you feel the ball holding very much, so I felt that the ball release was slow. The slower the ball is released, the easier it is to spin and control, but the pitch is only a small difference, but it slows down. On the other hand, Dignics 64 was faster than any other Dignics! Therefore, if you feel the benefit of putting pressure on your opponent at the speed of leaving the ball, you should definitely recommend Dignics 64.
Each technics
Fore hand
Light hit I didn’t feel any difference from other Dignics. However, I felt that I didn’t feel the tension of the rubber when I put it on.
Drive on long balls and rallies It was very easy to speed drive and was straight. Even with Dignics 05, it is easy to hit a straight speed drive, but Dignics 64 was more stable.
Drive with open face I felt that the ball was released a little faster. It may not be very suitable.
Top spin (loop) drive against back spin It’s not difficult to do, but I felt that the amount of rotation was a little unsatisfactory.
Speed drive against back spin I was a little worried about over mistakes, but I think it’s an arm problem.
Block It was easy to do. It will be difficult to rotate.
Counter drive Counter drive was good.
Stop / push It settled low. After all the amount of rotation is a little small.
Fore flick It was easy to do. It’s softer than Dignics 05, so I felt like I could grip it firmly and hit it.
Back hand
Light hit I felt the speed of leaving the ball a little. I also want to grip the back and hit it, and I also felt that it was a little difficult to do because I used outer carbon.
Drive on long balls and rallies It’s not bad, but the flight distance is quite long, so I just wanted to speed drive and I got a lot of unreasonable hits.
Top spin (loop) drive against back spin I made a few net mistakes, but I didn’t think it would be difficult.
Speed drive against back spin I made a lot of mistakes due to my lack of skill, but it’s easy to do.
Curve / shoot drive Chiquita was more powerful in the speed type.
Block It was easy to do.
Counter drive I’m not good at it, but I feel that I can do it if I practice.
Stop / push It was easy to do, but the amount of rotation is small.
Chiquita It was easy to do. Dignics 05 is hard and the arc line is too high, so it is difficult to feel, but I think that some people may find Dignics 64 easier to do.
Comparison with other rubbers (personal impressions)
ターゲットプロシリーズは、過去にTarget Pro GT-X51（ターゲットプロGT-X51）とTarget Pro GT-H47（ターゲットプロGT-H47）をレビューさせていただきました。この2枚は非常に打球感が良くて、硬度の割にくい込みが良さと扱いやすさを感じたラバーになります。ただし回転量がやや不足気味で、ターゲットプロGT-H47ではテナジー05より劣る、ターゲットプロGT-X51では回転量は高いが扱いにくいと感じた次第です。扱いやすさと打球感の良さは抜群に良いのと、スポンジの色が硬度で異なるのが触っていて楽しいラバーでした。
一方、近年の進化型ポストテナジーラバーは、シートを薄くできる技術（おそらくくい込みの良い新スポンジ）を組み合わせることで、回転量と打球感を損なうことなく高性能なラバーとなってきており、ターゲットプロXDシリーズも、高くなっている分、かなり性能の高さを感じるラバーに仕上がっていると想像して購入しました。逆にドイツ製ラバーに見られた癖球（ボールの回転量が揃いにくい）といったことが減ってきているようにも思います。 今回のTarget Pro XD-47.5（ターゲットプロXD-47.5）は、既にレビューしているTarget Pro XD-52.5（ターゲットプロXD-52.5）をより扱いやすくしたようなラバーだと思って購入しました。今までは同じラケットで試打してきたのですが、XD52.5はインナーカーボンラケットでも十分に扱いやすかったので、今回のXD-47.5はアウターカーボンで試打することにしました。どこまで扱いやすくなっているのか、楽しみです。
公表性能値
cornilleau（コニヨール）さんの公表性能値を示します。
Target Pro XD-52.5（ターゲットプロXD-52.5）はcornilleauのラバーの中で最もスピン性能もスピード性能も高いスピン系テンションラバーということがよく分かります。また性能や使いやすさとある程度の相関を示す、硬度計による硬度比較を下記に示します。
さてこのR45について、kastuo000はなんとなくですが、R48で相当シートもスポンジも柔らかいものになっていたので、R45ではスポンジ硬度は45°しかないので、シートを硬くするのではないか、となんとく想像しておりました。要はシートの硬い軟テンション系ラバーということですね。シートの硬い軟テンションラバーは、実は既に人気を博している（おそらくヨーロッパで特に人気の）売れセンのカテゴリーのラバーだと思います。katsuo000が確認しているシートの硬い軟テンション系ラバーは、TIBHAR（ティバー）さんのEvolution EL-S（エヴォリューションEL-S）、Joola（ヨーラ）さんのRhyzer Pro 45（ライザープロ45）、XIOM（エクシオン）さんのVega X（ヴェガX）などになります。どのラバーもシートが硬く、上手に扱えば高い回転性能を発揮してくれるラバーですね。それでいてスポンジは柔らかいのでくい込ませやすく初-中級者層向けの非常に扱いやすいラバーといえるでしょう。ただ上級者層になってくると、シートだけでボールをこすったり捉えたりしようとしたときにスリップすることがあるので、好みがわかれるラバーでもあると思います。今回のR45も、硬度計で硬度を計ると明らかにシートが硬く、要はシートの硬い軟テンション系のラザンター、というのがR45の立ち位置と言えると思いました。このR45について、androのパンフレットでは次のように紹介しています。
We would like to review Rosena, one of Butterfly (Tamasu)’s signature products. To talk about Rosena, I think it starts with Tenergy. The release of the world standard Tenergy 05 dates back to now, about 13 years ago, in April 2008. Tenergy 05, which still wants the name of the world standard even after more than 10 years have passed due to the prohibition of post-processing with organic solvents, has become an existence that can not be talked about without it when thinking about table tennis. Considering the features of this Tenergy series as katsuo000 as of 2021, I think it will be as follows.
Features of Tenergy series
・High spin performance
・High speed performance
・Weight light
I think that the characteristics of the Tenergy series as described above are largely due to Butterfly’s unique sponge. The sponge used in the Tenergy series is an orange sponge called Spring Sponge, and the bubbles in the sponge have a closed cell structure, and it seems that they are able to show high performance. This spring sponge is a technology that differentiates it from other competing table tennis makers with only Butterfly technology. While other competing table tennis makers basically outsource rubber manufacturing, Butterfly, despite being a table tennis maker, owns a sponge manufacturing factory and is trying to differentiate itself. Because of this spring sponge, Tenergy can produce high performance, but due to the fact that it costs research and development in addition to resale and counterfeiting, it has become an open price and it is almost double the price compared to other rubbers. It can be said that it is also a (bad) feature. However, there is no doubt that the usage rate of top players is high and it is the world standard. In addition to Tenergy 05, which has the highest usage rate of the top players and high rotation performance, Tenergy 64, which has high speed performance due to the difference in the top seat, Tenegy 80, which has a good balance of spin and speed, There are 5 types of seats, including the Tenergy 25, which is strong against counters and front teams, and the Power Tenergy 19, which was released the other day. The explanation of each sheet is as follows.
No. 05: 1.7 mm grain spacing is narrow. High rotation performance. No. 25: The height of the 2.65 mm grain is low. Easy to play on the table and counter. No. 64: 1.7 mm wide grain spacing. High speed performance. No. 180: The grain spacing of 1.7 mm is in the middle. The rotation and speed are well balanced. No. 219: 1.5 mm grain spacing is narrow. It is easy to grab the ball well and put out power. As mentioned above, the characteristics of each top sheet are reflected, and there are key phrases such as “Rotation 05”, “Balance 80”, “Speed 64”, “Front 25”, and “Power 19”. It is crowned.
About 13 years ago, after launching Tenergy 05 in April 2008, Butterfly launched Tenergy 25 in November 2008, Tenergy 64 in April 2009, and Tenergy in July 2010. 05 FX (Tenergy 05 FX), Tenergy 25 FX in November 2010, Tenergy 64 FX in November 2011, Tenergy 80 in January 2013, 2014 Tenergy 80 FX in April 2017, Rozena in April 2017, Tenergy 05 Hard, which is a harder version of Tenergy 05 in November 2018, in April 2019. Dignics 05 has been released as a rubber that exceeds tenergy. And in March 2021, when the transition from Tenergy to Dignics was beginning to appear, Tenergy 19 was put on the market. To date, there are 10 types of Tenergy. Each has been sold as a new product, and the fact that Tenergy 05 is still popular is a sign of completion and trust.
Rosena, reviewed on this page, is, so to speak, a cheaper version of Tenergy. Combined with a soft spring sponge, it becomes an easy-to-use tenergy-like rubber. I think it is a popular rubber as a back rubber for intermediate users or as a rubber with a spring sponge for the first time for beginners. In terms of price range, it is cheaper than the signboard rubber of other manufacturers and cheaper than the best-selling rubber, Fastarc G-1 of Nittaku, and the real selling price is fiercely competitive 4,000 It will be a rubber dropped on the circle! For cheaper and better performance than this price, Yasaka’s Rakza series and Rigan, and XIOM’s Vega X and Vega Tour 3,000. Will it be a round rubber? I would like to make a comparison with this area in the future. Recently, a review of Rosena was posted on YouTuber, Goblin’s, but it was quite badly criticized. I think she has some likes and dislikes that don’t meet. I think she feels uncomfortable using hard rubber.
Published performance value
Shows the published performance values of Butterfly.
It may be no exaggeration to say that Rosena is Tenergy 05, which has inferior spin performance in a sense. Actually, I tried it again this time, but I have used thick Rosena in the past. In that impression, I had a strong impression that it was a rubber with low rotational performance. On the other hand, I remember that the shot feeling was certainly the shot feeling of the spring sponge, and the feel was not bad.
Rozena weight and paste
Rosena weighed 48 g. Butterfly’s rubber seems to have a correlation with sponge hardness basically, and the Tenergy FX series has softer sponge hardness and lighter weight. The sponge hardness is 35, which is a little softer than Tenergy, so 48 g is a heavy weight.

Three features of Rozena
Recently, I mainly use Tenergy rubber for the back, so I could use it with a good feeling rather than a very strange feeling. To be honest, I could not deny the lack of power, but I still felt that the ease of handling was higher than the Tenergy series and Tenergy FX series! It was a level that I was wondering whether to use it in the main. I think it’s a shield-like rubber for sticking rather than using it as a weapon. If you want to attack, it’s like playing a little at the counter or block using the opponent’s ball to meet. The current candidates for back rubber were Tenergy 05 and Rakza X. Compared to Rakza X, Rakza X tends to be heavier due to individual differences, so it costs around 500 yen, but I felt that I liked Rosena better. Of course, the quality of loop drive and push is higher than that of Rakza X and Tenergy 05, but I think Rosena is better in terms of total balance and ease of handling.
Anyway, various techniques are easy to do!
To be honest, I didn’t expect it so far, but I didn’t have any difficult technology. I felt like I was holding the ball a little too much, but it was very easy to do loop drive, speed drive, block, counter, stop. I personally found it easy to do with blocks, which was pretty easy to do! I felt the flexibility to enter if I hit it. There was a feeling that the entire rubber absorbed the power of the opponent’s ball. The only thing I felt was that when I tried to take the ball with just the seat, it felt like a slip, and I felt that this part was difficult to handle. I felt that it was a rubber that was firmly bitten into the sponge and hit.
The rally of the upper spin gives you a feeling of spring sponge!
At the time of the rally of the upper rotation, by playing while driving and biting while biting in, it was possible to reapply the upper rotation and it felt like it would fit on the opponent’s court, so it was a good impression. With Tenergy 05, I feel like I’m going over or going to the net if I don’t drive more. It is Tenergy 05 that makes it easy to feel the hardness, and if you just hit it, it will be difficult to exert power and you can only get a good ball by flying while rotating firmly. On the other hand, Rosena fits well just by playing, and it may be said that there is a part that seems to be Tenergy 64 or Tenergy 80. I don’t have any definite information about the grain shape of the sheet, but I think it’s a sheet that is closer to 64 or 80. Therefore, it was easy to hit a ball that accelerates while drawing an arc with less energy in the upper rotation rally. I think this arc and acceleration are like spring sponges. I think that being able to put out such a ball is a characteristic of Rosena and a good point.
Bring the ball with good bite!
I think the grain shape of the sheet is close to 64 or 80, but the sponge is a little soft and grips the ball very well. I felt that it was close to Tenergy 05. Therefore, it was easy to hit the loop drive. However, I felt the need to hit while considering the flight distance to some extent because it does not sink completely by rotation, not the feeling that anything can be entered by rotating and flying. This area seems to have different tastes, but I am convinced that it is a spring sponge rubber suitable for beginners and intermediates. I think that the good points of Tenergy 05 and Tenergy 80 (because katsuo000 has never used Tenergy 64) and the desired parts coexist in a well-balanced manner. From this Rosena, I felt that it was a rubber that could be changed to each Tenergy in order to use my own characteristics and frequently used techniques as weapons. On the other hand, I certainly felt disappointed when I wanted the features of Tenergy 05 and the features of Tenergy 64 as they were. Since it is a balanced type, Tenergy 80 may be the closest. I think it is difficult to obtain sharp performance. It’s a very well-balanced rubber, and I thought it could be recommended for Penholder who have to do anything.
Each technics review
Forehand
Light hit You have a ball. I felt that it had a lot of spheres compared to Dignics 05.
Rally drive It’s not particularly difficult to do, but I felt like I was going too far to the foreside because I had a ball. Is this used to it? Since the amount of rotation is the first time when it is bitten in, I felt that it was easy to apply rotation in the upper rotation rally and it could be dropped by rotation. Is this a place like a spring sponge?
Backhand
Light hit It was very easy to do. It was a good impression to have a ball and the rubber absorbs it even if you push it unreasonably, so even if you push it forcibly, it will enter quite a bit. I think this is the one you can count on in the game.
Rally drive Since the backhand is not good at my arm and footwork, the hitting point is easy to move back and forth and it is unstable, but Rosena was very nice with the rubber that absorbs the front and back of the hitting point. The quality may be low, but I was happy that I could get it if I tried to put it in anyway. Also, he was very easy to drive in front of the top of the front team and did not feel bad.
Loop (top spin) drive against back spin Since it has the same ball as Tenergy 05 and Tenergy 05 FX, the ball quality is low, but it feels easy to control. I think that it is a rubber that is easy to make a loop drive of such a connection that connects firmly and attacks the next ball.
Speed drive against back spin It was easy to drive speed because it was good to bite to some extent. Although I can’t expect the ball to sink as much as the Tenergy 05FX, it was a rubber that made me feel like I was hitting it.
Block It was the block that I felt was the best compared to Tenergy 05 and Tenergy 05 FX. It was very easy to do and I was impressed. I think that the sponge is hard and the sheet is insensitive to the rotation of the other party in a good way.
Counter drive I was impressed by the feeling that the counter was stable enough even if I caught the front of the top a little like meat. I think that it is a rubber that is a little difficult to drop by rotation, so on the contrary, I think that it is a rubber that has a meat-like way of hitting. I don’t think that the back is counter-driven by taking the plunge, so I felt that it was a rubber that fits the back in that sense as well.
Stop The only thing I found difficult was the stop. It’s easy to play, so if you don’t touch the ball in a short time, I feel that it’s easy to receive the rotation of the opponent directly.
Push Like the stop, it was difficult to rotate. It was a little difficult to bite in too well and overshoot, or slip on the contrary and make a net mistake.
Chiquita It was easy to give and easy to do. However, I felt that it was not very powerful. If you are looking for power, it will be the Tenergy series.
Comparison with other rubbers (personal impressions)
Spin amount Tenergy 80 FX ＞ Rozena ＞ Evolution MX-P
中国製粘着ラバーということで、初めはフォア側で使ってみました。普段使っているOmega VII China Ying（オメガVIIチャイナ影）と比べるとかなり柔らかく感じました。そこで、バック側でどう感じるか試してみたら抜群に扱いやすくて驚きました。ボールをしっかりグリップするし中陣からでもドライブもしやすく非常に好感触でした。球持ちが非常に良いのでループっぽく入れに行くのもやりやすかったです！
Rakza Z Extra Hard（ラクザZエキストラハード）をレビューします。このラバーはYASAKA（ヤサカ）の久々のハイエンドラバーであり、粘着テンションラバーになりますね！2020年Butterfly（バタフライ）が最新粘着テンションラバー、Dignics 09C（ディグニクス09C）を発売したタイミングで、ヤサカも追いかけるように発売したのがこのラクザZになります。ラクザZには硬度が2種類あり、約50°くらいのラクザZと、ヤサカのラバーの中でも一、二に硬い55°くらいのラクザZエキストラハードになります。本ページではラクザZエキストラハードをレビューします。このラバーのユーザーは早稲田大学卒業後、TT彩たまに入団した五十嵐 史弥選手、最近ではヤサカの看板選手でTT彩たまの神巧也選手になります。またYou Tuber、ごぶりんずのヤンマさんも使用中のようですね。
ヤサカの契約選手といえば、2014年に全日本選手権準優勝した神巧也選手、2019年世界選手権準優勝のMattias Falck（マティアス ファルク、Sweden）選手、アドバイザーでワールドカップ優勝4回、アテネオリンピック優勝の馬琳（マリン、中国）選手が有名ですね。また関東学生選手権優勝の五十嵐史弥選手、全日本選手権大会ジュニアの部優勝の笹尾明日香選手、関東学生選手権準優勝の加藤結有子選手と早稲田大学の契約選手も多いです。また異質の裏裏カットマンでTT彩たまで活躍中の英田理志選手と多数の尖がった契約選手が多いです。神選手は学生時代含めるとRakza 7 (ラクザ7)、Rakza X (ラクザX）、Rising Dragon (翔龍)、ラクザZエキストラハードとまさにヤサカのハイエンドラバーを順番に使い続ける選手ですね。トップ選手だけでなく、アマチュア選手でも多数の選手がラクザ7、ラクザX、翔龍は使用されており、非常に有名なラバーだと思います。ラクザZもあっという間に広がりそうです。
細かくラクザシリーズを説明していくと、4種類のラクザラバーが存在し、それぞれ細かく異なります。ラクザZには、ラクザZとRakza Z Extra Hard（ラクザZエキストラハード）の2種類が存在します。ラクザXは、Non Slip Sheet（ノンスリップシート、NSS）技術が採用されていて、他のラクザと一線を画す、高いグリップ力を持つそうです。性能値で見た場合には回転量はラクザZの次にラクザ7の方が高い値になっていますね。そしてシリーズ最速となるのがラクザ9になります。またスポンジが柔らかいソフトはラクザXとラクザ7の2種で販売されています。このように細かい部分で異なる部分を有しながらも非常に人気の高いラバーシリーズがラクザシリーズということになりますね。 今回レビューするラクザZ EHは、バタフライのラバーの中ではディグニクス09C系のラバーということで、ラクザZ EHの粘着テンションラバーとしての性能を確認していきたいと思います。
ラクザZエキストラハードは重さはかなり重い一方で硬さはテナジー05なみの硬さという結果になりました（shore c sheetの結果より。）。ただしYASAKAのラバーは硬度の割にくい込みが良い、ということもないので、感覚的にはディグニクス09Cと同程度には硬いと感じるのがラクザZエキストラハードになります。 また特徴的なのが、shore aのシート側とスポンジ側の差で、要はシート側の方が柔らかく、スポンジ側の方が硬いのがラクザZということがわかります。ディグニクス09Cやスピン系テンションラバーと言われるラバーは、シート側が硬く、スポンジ側が柔らかいというのがセオリーのようですが、ラクザZや中国製のキョウヒョウはスポンジが硬くシートが柔らかいというのが粘着ラバーの特徴といえるのかもしれません。シートが柔らかいことでループドライブの質を高くしやすい印象がありますので、ラクザZエキストラハードには、ループドライブの良さを期待できそうですね！
ラクザZエキストラハードの貼りと重量
ちょっとわかりにくいのですが、ラクザZエキストラハードのスポンジは気泡がかなり入ったスポンジです。この気泡の多さはまるでスピン系テンションラバーのようですね。（黒いスポンジはOmega VII China Ying（オメガVIIチャイナ影）になります。）ディグニクス09Cも気泡は確認できますが、かなり気泡が細かいです。またキョウヒョウはほとんど気泡が確認されないようなスポンジですね。このあたりがラバーの違いとして現れそうだと感じました。
貼ったラケットはキョウヒョウ301になります。インナーラケットですね。やはりドイツ製粘着テンションンは全体的に弾むので味を出すならインナーカーボンが最適だと思います。またはラクザZエキストラハードであれば、ヤサカの契約選手のように木材合板でしょうか。7枚合板のMa Lin Extra Special（馬林エキストラスペシャル）などはかなりオススメになりますね。 また粘着感は、ディグニクス09Cやドイツ製粘着テンションラバーと比べると、強いです。翔龍と比べると同等か、少しラクザZエキストラハードの方が弱いかな、って感じました。ディグニクス09Cや最近のドイツ製粘着テンションのシートが全然粘着らしさがない中で、ラクザZエキストラハードは強い粘着を感じるのは粘着ユーザーとしては嬉しかったです。
中間硬度ということでテナジー05はもちろん、MX-P、MX-Sよりもあきらかに柔らかいですね。シートは硬い感じです。今後も触れると思うのですが、このEL-Sは、Joola（ヨーラ）さんのRhyzer Pro 45（ライザープロ45）、Rasanter R45（ラザンターR45）などのラバーにかなり近いと感じました。これらのラバーの共通点はミドル硬度のスポンジで、シートが硬いラバーになりますね。
