Yasaka, using mainly natural rubber gum for the top sheet. This improves the level of grip and the power of spin drastically. The top sheet is combined with the new Power Sponge. The top sheet and Power Sponge work in perfect synergy, producing the Hybrid Energy rubber Rakza 7. When the player hits the ball hard, the rubber grips the ball and the stroke can be used to place the ball accurately, both in direction and length. The serve and short returns are very sharp and easy to handle. Due to the increased percentage of natural gum the durability is improved. A winning combination!

Switched from Glayzer. The speed on speed drives dropped a bit compared to Glayzer, but control feels better. It goes in whether you just hit it flat, brush it, or really let the ball sink into the sponge, so it should suit a lot of different players. The biggest appeal, though, is the spin on loop drives. Other reviews, blogs, YouTube, etc. tend to say it's not that strong, but it actually has plenty of spin, if not more. Serve spin is also high, and if you relax and barely move anything but your wrist, you can get some really nasty spin serves. Honestly, just use this instead of other intermediate-level rubbers (the Glayzer series, Rozena, Vega series, etc.).

This is a good, affordable first German tension rubber if you want to compete on spin without bouncing too much.
I'd recommend it for choppers who fit that description.
You get a real sense of driving the ball with your own power, control is easy to add, and every technique makes it easy to put on spin.
Personally, I think it can play a real part in helping beginner-to-intermediate choppers improve.
The sponge being soft and light is nice too. It's also easy to keep hard hits under control with chops.
It's easy to create an arc, and drives feel stable too.
I'd say it's about as close to a perfect all-rounder as it gets.On the other hand, receives might be more easily affected by the opponent's spin.
Also, the ball quality on offense might feel a bit light (or rather, the spin comes out "honest")? I normally use DNA Pro H as my main rubber and thought it might be a bit too hard,
so I tried out Rakza 7, which I'd been curious about for a while but never used,
and I did feel there are some downsides on offense with it.
(This is purely a comparison — under normal circumstances it still puts out plenty of power.)
It might actually pair well with a hard-type blade or a lively, bouncy blade.
Once you get used to it, moving up to the Z is also an option.
*Addendum
It pairs really well with Masamune, so give it a try.
It's a rubber that matches surprisingly well with the sticky, clingy feel of a three-ply hinoki blade.All Speed Spin Control Hardness Little soft

For better or worse, this feels like a rubber where putting spin on the ball is mandatory.
If you can hit it while brushing properly, you get a great shot, but if you hit it more like a flat contact, it flies way off.All Speed Spin Control Hardness Little soft

Every technique is easy to pull off.
Drives against backspin especially became very stable.
It's easy to handle and the ball goes exactly where I intend.
I'm a chopper and switched over from a tacky rubber, and I found chops easy to keep under control too — overall it felt like a well-balanced rubber for both offense and defense.
Pushes come out flat, though, so it took me a little time to get used to that.All Speed Spin Control Hardness Little soft

(Experience: ６〜１０ years) An average 47.5° rubber, for better or worse

I used the 2.1mm version.
The sponge is a bit firmer than medium hardness, but the sheet is on the softer side and the ball sinks in easily, so it feels more manageable than its rated hardness would suggest.
Because the sheet is soft, brushing-type spin techniques are easy to do, but the arc is on the lower side and the depth of the shot tends to be a bit shallow.It has a consistent level of ease across every technique, so I think it makes a great benchmark for the 47.5° hardness class.
If you want a higher arc, Rakza X or Dignics V47.5 are options; if you want speed or a flatter trajectory, V>15 Extra or Rasanter R48 — it's easy to find your next step within the same hardness range.It didn't hit me with the same impact as Rakza XX or X Soft, but it's a good rubber for German-tension users looking to move up from the 42.5-45° range.

On my forehand, I switched from Rozena to max-thickness Rakza 7. Compared to Rozena, I was shocked at how ridiculously easy it was to drive-lift backspin. And the speed was fast enough that I could really feel it. Serves were easy to spin too, so overall this was a very satisfying rubber.
Highly recommended!!All Speed Spin Control Hardness Little hard

For intermediate-level players, this one rubber alone can cover everything you need.
Both the sponge and sheet are just the right amount of soft, so mistakes are rare, and it's easy to pull off speed drives, loop drives, and receiving in general. It also pairs well with all kinds of blades. That said, putting it on a lively blade like an outer-carbon one can make it feel harder and less usable, so I'd recommend intermediate players try it on a wood or inner-carbon blade.All Speed Spin Control Hardness Little soft
