唐橋卓球別注のラティカになるそうです。ラティカといえば、Nittaku（ニッタク）の定番5枚合板ラケットで、佳純ベーシックをベースに、ブレードを少し大きくすることで、ブロックと攻撃の安定性を強化したモデルです。特に卓球王国さんでは、中国式ペンをおしていました。Latika（ラティカ）そのものはブレード面積が広いようですが、中国式のLatika NK Cはコンパクトで丸みのあるブレード形状で重心がグリップ側によることで振り抜きやすくなっているそうです。
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.
