Averages reviews points
The first rubber to be introduced with Yasaka’s Hybrid Energy system was the Rakza 7, which is highly valued by high class players all over the world. The latest addition to the Rakza family is Rakza 9, which has improved speed characteristics. The surface rubber of Rakza 9 has a newly developed formula/rubber combination. In addition the new sponge is made of a more homogenous material and has larger pores. Rakza 9 is the fastest of Yasaka’s Hybrid Energy rubbers and is suitable for technical offensive players, using both high speed and spin to win the point.

Toma （Experience：４〜５ years） Easy to use, even for beginners!
But difficult to use in the foreground to exert tremendous power in the back. In addition, easy to use from beginner easier also, such as Chiquita and flick to advanced.

When I bought it, it was a very good rubber. We used for back, but speed of speed drive, depth were marvelous, and we entered small arch line and entered stably. When the back drive came in, it hardly returned.
Although Tsutsuki and the like float somewhat, since rotation takes place firmly, it was a ball that invites the other party's mistake on the contrary (laughs) The technology using the goodness of separation such as flicks and blocks is the best.
However, it is the life expectancy. In the case of tension rubber, I always clean with a rubber cleaner and put a film. However, after two months, all speed drives that had been decided so far hit the net. I think that probably the hook falls and the arc disappears.
Personally, I felt that continuous use was tough.

Rakuichi Rakuza （Experience：２〜３ years） Sounds good
I did it in the back I can easily hit the Chikita It is a rubber that blocks or counters in the front row anything
All10/10 Speed10 Spin9 Control9 Hardness Little soft
Racket recommended use ETERNITY VPS V
Takuto （Experience：２〜３ years） Well. .
I did not think that it was a very good rubber personally. It seems that something was forced to speed up. . . A player who can completely control is as strong as a demon. In fact it was made to be battered. . .

Racket recommended use Inner force layer ALC.S - CS
Pig cat （Experience：４〜５ years） Convinced why the user is few
I put up with this rubber back for a week and used it, but I could not handle it.
Although meat, block-based technology was awesome, trying to connect the middle ball lightly would become a ball and net mistake.
It is a very difficult rubber as other people wrote.
It was difficult for Tsutsuki to float out downward rotation.
It was a very nice rubber in the sense that I was keenly aware of the ease of use of C - 1 that I was using.

poiuytrewq （Experience：６〜１０ years） Hard rubber
I do not feel much stuck.
Drive is pretty arcuate, low speed fast and difficult to pick ball. Although it does not mean that the rotation is not applied, clearly the rotation amount is inferior to that of the spin type rubber.
The ball of the meat type got speed and it was powerful.
The block is easy to do because it is hard to be affected by rotation.
Serve receive is honestly not turning much. However, in Saab, the speed system is fast and there is the merit that the receive is not influenced by the rotation.
Taiko play was a better feeling, such as a quick tokki, than spinning from himself.
I think that this rubber is a rubber that is quite highly evaluated. Honestly, it is not suitable for those of a battle type like hanging a rotation, hitting a drive by going down. There are quite a few people in the battlefield who are attacking with the fast pitch in the former team.
However, if a person who rubs firmly can use a ball that is difficult to take, it is a rubber like a blade of two blades that will be caught on the net if it can not be used, so I think that it is a rubber that picks up the user.
Personally I stuck this rubber on the back, I felt it was effective to stick adhesive rubber on the fore and attack by the difference in rotation amount.
All7/10 Speed9 Spin5 Control5 Hardness Little soft
Racket recommended use SK7
Black Storm hybrid
The arcuate line is low and it bounces by the amount of force transmitted.
I can also feel that it is speed design but does not reduce rotation performance as much as possible.
There is a feeling that it jumps too much when you hit it, but I think if there is a problem if I get used to it a little. Since the seat grips properly, meat can be struck with confidence.
You can use it on the fore and back, but rather back is recommended.
