I hover between the Rakza7 and Tenergy 05 on my forehand. Rakza is slightly better for smashing while Tenergy is slightly better for looping. R7 is great for serves. Pushing I probably prefer Tenergy 05 a bit more only because I prefer the Timo Boll ZLC blade it is on. While the R7 is on a Stiga CarboKev blade. Both rubbers have good dwell time with T05 only slightly longer due to its spring sponge. All in all Rakza 7 is a top class rubber and I thoroughly recommend it. The key is to ensure you put it on a blade that suits your play.

In the first time in very hard, but after 1 week the sponge transform in medium hard.

the rubber have very spin and is fast in special to smashing.

Is very good to shot topspin and attack in straight path. easy to control. realy is good rubber.

I use the rubber with Michael Maze (arilate carbon)

get used to it and you'll have a predictable straight to the point controlled game. amazing.. try!!!

alternative for t05 and even better coz the sponge is slightly softer still hard enugh for smash :o)

I m yasaka fan since mark v time. Now i bought this new generation from yasaka. I really love it's consistency of control and spin. As yasaka rubbers are very good in control, this razka 7 produce really good control. razka 7 can produce more spin than mark v for both rally and serving. Overall it's the great rubber. Recommended for all higher level players

Use it om my bh. 1.8mm. Very Good rubber. Little bit slower than tenergy. I have tenergy 05 1.0 mm om fh. My blade is à waldner senso carbon.

I have tried t05-Acuda S1-Baracuda-hexer all on fh of andro all+ blade rakza 7 has more spin than all rubbers listed speed is second to Acuda s1 throw is high like t05 7 has more control than hexer and t05 same as s1. My ranking in spin.

I try this ruber in RSM platinum specail and cypress Max, and I found the rubber is fantastic in both spin and speed. The serve is easily control and can make a deep or speedy serve, the receive is also fine. The durability is average. The onlcy concern is the gluing. more glue is needed to stick the rubber to the hinoki blades

Fantastic rubber, I put 2 rakza in a Timo boll spirit and is very spectacular.
Is very fast with a lot of spin.
For chop is very good with a lot of control and spin.
To do topspins is amazing.
I recomended this rubber for backhand and forehand specially for players with a medium-high level.
Very good rubber!!

An excellent rubber that i would recommend to any blocker or attacking player . Great combo of spin and speed , with the extra grip of the ball providing greater control .

Well, this rubber may be a little hard to get in the start because of its speed. But after some trainning sessions, it begins to be quite easy to play with. The throw is medium-low. Spin? High, mainly in sidespin loops. Is it a good alternative to tenergy? YES.

I like this rubber. It has excellent speed, spin and control. I strongly recommend it.

A great choice for mid level to pro. An advanced rubber with powerful loops, drives and smash. Very fast rubber that has many grears and great spin. Takes several training sessions to tame this beast but plays much like BTY T05 without the high price of T05. Outstanding for mid distant looping. Good feel with service returns and blocking. 1.8mm best to start with. Outstanding quality.

it's the best yasaka rubber. it's incredible! i love it! it's very fast and halucinative spin. all with very very good control. i recomend this with an off blade and you creates a fantastic bat. and because it's natural gum the rubber lasts a very long time!

this rubber is a very good rubber it has sublime control you can destroy your opponent with heavy spin serves topspins blocks re-topspins this rubber is one of the best allround-rubbers in the world everyone can play with this!!!

Wow! This is the rubber I have been looking for my BH! It grabs the ball and returns it with a vicious spin wherever I want on the opponents side! And now I can generate very short, close-to-the-table, low-throw and threatening loops, backspins or undercuts. Congratulations Yasaka!

I had Rakza7 for quite some time on my Andro OFF+ blade, but mostly played with other more defensive blade (I like to chop). Recently by chance, I started looping with the Andro OFF+ with Rakza7 and wow, it has a lot of spin. You can lift the heavy backspin with it fairly easy. Compared to Tenergy, it's a bit more softer and tackier and it feels lighter than Tenergy. I like the fact that if you block with it, it takes the opponent's spin and reverses it pretty well, so the ball doesn't fly over the table if you block heavy shot with a little upwards move.

I am a long time tenergy 05 user, and this rakza rubber will now be replacing it. The spin is huge, like the t 05, but control seems much better. The tenergy would get a little wild in high speed/spin exchanges, where the rakza seems a bit more stable. It's got the qualities I like about the t05-the outrageous spin, without the qualities I dont- the price and the unpredictability. At half the price of the tenergy, it's more than worth the money. Excellent product

i used and trust Mark V rubber, i think i should try this one...

I spent a bit of time looking an alternative to the Tenergy rubbers. Rakza 7 is not an alternative... its better!
It gives you all the qualities of T05, with more control and at half the price. It was a pretty simple decision for me.

Fantastic rubber!
Is very fast with a lot of spin.
Very good control.
Topspins and chop is very good. Also impressing is the serve-returns. VERY fun to loop with.I recomended this rubber for forehand, but it is good on the backhand too.

Good Rubber. Not very durable. Now it is very smooth, after 6 months. In the begin a very spinny rubber, but after some time it is useless.

A very complete rubber. High spin and very fast. It takes time to control it but when you do it is a deadly weapon. Also is quite heavy so isn't a good idea to glue it in a heavy blade. What I really like of this rubber is its consistency. You can do almost everything good with this beauty!

My backhand rubber atm. My originall backhand rubber was DHS Skyline 3 Neo and it was good. But I had an injury and wasn't able to play for 3 weeks. After that pause, my Skyline 3 was completelly different. Much slower (it was almost like a def rubber), weird sound. I tryed to reglue it but it didn't help... My forehand Skyline 2 Neo survived that pause well without any problems, really dunno what happened. After that, I started searching some alternatives. Tryed Donic Baracuda, Xiom Vega Europe and Rakza. Rakza is the best of these rubbers for me. It's sponge hardness is medium-soft (if you check the ratings, you can see that DHS Skyline 2 Neo should be softer - 5.1 comp. to Rakza's 5.8. It isn't correct at all, just try to press both rubbers between fingers and you can see Rakza is significantly softer. Another example why you shouldn't believe in the ratings here). It produces decent spin but it isn't a spin monster like Skyline or Tenergy (+- same as Baracuda, much more than Xiom Vega Euro). Speed isn't high, almost the same like Skyline 2 Neo or Baracuda. Controll is good but you can get rubbers with better ball feeling. It performs best in mid distance looping, slightly worse in fast drives and close to the table game. It is a good rubber overally but I think I'll not keep it for a long time.

EDIT (November 2011): I've changed my mind. I'm keeping Rakza, it rocks. Good speed (not extra fast, slightly under Tenergy 05), ideal throw angle, awesome controll and pretty good in looping. Ok, spin is slightly lower comparing to DHS Neo rubbers but you don't need so much effort and power to get a ball over the net from a strong chop. I have Tenergy 05 and Rakza 7 on my blade atm and Rakza dominates in everything. I'll remove Tenergy soon, 2nd sheet of Rakza is on a way to me. I recommend it to everyone who is looking for a Tenergy alternative, it can work better! I'm a proof of that.

EDIT (December 2011): I use this Rakza on my forehand side, replaced it by Stiga Boost TX on my backhand. The reason is simple - it's throw angle was too high for my backhand (lower than Tenergy's anyway). On the other hand if it's throw was higher, it could be a 10/10 rubber for my forehand. It is because I usually play mid distance forehand loops, oftenly fighting with opponent's strong chop. I can handle that but the throw angle for that could be slightly higher for perfection, something between T05 and Rakza. But nothing is perfect, Rakza is an awesome rubber.

EDIT (December 2011): I'm back with Rakza on my backhand. I was thinking about it for a long time and this is better. Rakza's attacking potential is higher and as a both winged looper I need more spin and speed from the mid distance. Boost isn't bad but it is much worse in mid distance looping. It's about a compromise.

EDIT (Feb 2012): My forehand Rakza didn't last longer than 3 months. It is an awesome rubber but it doesn't last ages if your style is agressive.

EDIT (Feb 2012): After many test I've finally stabilized my setup. Rakza is the best offensive rubber I've ever played with. Using both rubbers in max thickness atm but I'll buy the 2.0 version on my bh next time. Many people prefer Tenergy but I don't. Rakza is better in everything from my point of view.

This rubber is realy realy realy great for players who likes to play allround + this rubber feels like tensor and has a great sound and is controlled like Something Strong specie ... Great for every kind of play :)

My preferite rubber for forehand. Good speed, a lot of spin. Very great rubber.

i just bought this rubber like 3 days ago and let me tell you is the best rubber ever for your backhand simply amazing...

i use it on fb the soft version on bh...this thing is fast and spinny!!! good control better than tenergy ...more linear than tenergy ...meaning better short game

I m a medium player using innerforce zlc. Before this i used tenergy 64 for both side. Cant control it. Its too fast for me for the fh.
R7 is great for me. It not as fast as T64 but just nice speed. The smash just amazing. Faster than T64 and xiom pro.block i prefer t64. Control very good compare to t64. I think its an arround rubber. Easy to play with it

The rubber is great but the throw angle is so high that only after i returned to my coppa platin rubber i understood how much it destroyed my game.... I used it on Mazunov blade and i had to sell the rubber.

highly recommended!!

very nice balance in speed spin and control, make playing getting consistancy.

i am not a very pro, but this is great.

use in my FH to replace my DHS H3 Neo..take sometimes to change from chinese loop style to euro/jap style..after get used to it, it feels like i tamed the beast...really good rubber

Using with Stiga Offensive NCT 2mm on FH. Huge spin on serves and opening loops. I can generate great spin with this rubber. Sponge is medium, feels around 35. Good speed and power for FH away from table. Control and short game good for tensor

pro rubber, if you make mistakes is your fault, don't blame it;D fast, resistant, high spin. cool rubber. exactly what i've expected.

One of the best rubbers I've used. Consistency is the key point of this rubber. Yes it provides speed and spin to your shots, but it is very consistent. You can almost rely entirely on this rubber to land shots on the table. Good forehand rubber.

I put it on TBS for FH. I have tried many rubbers to replace T05 and spent lots of money. This is the one I will say it's T05 replacement. The throw angle is lower but practicing will comfort your style.

Just got it today. Very nice.
Pros
Easy return of chops and pushes
Very spinny serves
Nice for blocking
Cons
Hard to control in the beginning

Great rubber! My style is attacking game on both wings, with active blocking and counter hitting.
After trying various rubbers (T64, T64fx, T25, T05fx, Andro Hexers, Palio Thor, Xiom Omega IV Pro and Europe, to mention just a few) I've found the best backhand rubber in Yasaka Rakza 7. I've been using it for 5 months now. I started with max, then 2.0mm but 1.8 mm has been the best so far. It is difficult to source (1.8mm) in Europe thou. Import from US is a bit pricey but worth it.
It offers perfect feel for short play, return of the serve is well controlled. It is fast. For me the Max is too fast for controlled game. However, 1.8 is fast enough for very effective attacking bh push. But the real advantage comes when you want to play an opening loop against the chop. So easy! BH top spin with this rubber is decent too, max or 2.0 is more suited for this shot. Whichever sponge thickness you choose it will give you a lot of control, but 1.8mm gives you the most in this department. It has an ideal throw angle for backhand, not too linear, not too high. Again if you play close to the table, or up to 1m away, 1.8mm is perfect. If your game is further away go for 2.0mm, or max. Blocking is easy and well controlled with any sponge thickness. I've tried Rakza 7 SOFT 1.8 as well. However, my personal preference is Rakza 7 1.8mm. But then I've always liked medium hard rubbers...
It's a perfect match to BF Innerforce ZLC and for me works the best with BF Tenergy 05 1.9mm on the other side. That's my league set up. For fun play I use Innerforce ZLC with Rakza 7 2.0 on bh and Tenergy 05 2.1 on fh. Try it you won't be disappointed.

I love the Rakza series. I use the Rakza 7 2.0 mm on my BH. There's plenty of spin and speed for my strong, flicky stroke, and provides nice spin in my serves. On my FH, I find I need just a tad more dwell time, so I use Rakza 7 soft in max. I have been using Rakza for almost a year and a half, and haven't found anything I like better. It's durable, spinny, and has a nice throw angle, yet handles chops and pushes without the catapult effect you get with Tenergy.

Outstanding rubber with great speed and spin without jeopardizing good control of the ball!

Been trying out a lot of rubbers recently (Rasant, T25fx, Hexer Duo, Acuda S2 & T80), but Razka 7 is the best of the lot. I heard it was great, but I have been surprised by just how much control you get, particularly on the block, for such a fast and spiny rubber. Great for BH or FH. Highly recommended.

a lot of people say its better then tenergy and i agree. you never get tired of this helpful tool and is unreplaceable. Its way cheaper then tenergy and its worth it
