This is a review of the Yasaka Rakza 7 Soft rubber in the color red, max sponge.
Blade: Stiga Hybrid Wood penhold
Initial observations:
Top quality topsheet.
Soft springy sponge in the color white.
Weight is avarage. Not as heavy as chinese rubbers.
Throw:
The Rakza 7 Soft I would say has a medium to low throw. Lower than chinese rubbers like the H3 Neo and TG2 Neo, lower than the Rakza 7 but slightly higher than Stiga Boost XT.
Compared to Rakza 7 the sponge is "bouncy" and the throw gets a boost. The throw length is perfect for my forehand game, feels really "safe". The springy feel does not suit my bachand game, but I will try to give it more time.
Speed:
Not a fast rubber, however the sponge provides bounce enough to balance the spin and is a big part of the rubbers exelent control.
This rubber is about as fast as the H3 neo was on my blade, but for different reasons. The H3's tacky topsheet needs a huge effort from you to generate speed, so does this rubber.
As a forehand rubber, the speed and bounce could be better. Perhaps the R7Soft would benefit from a softer blade, just like the H3 Neo did. Will update the review once this is tested. (Not hapening soon!

)
[edit] After a few weeks I glued this rubber on an old Banda JO Waldner blade and this blade suits the Rakza rubbers much better. The speed was increased noticably! [/edit]
Spin:
Good amount of spin thanks to the top quality of the topsheet. The topsheet is a little tacky, it picks up a small amout of dust but not much. Easy to clean.
Control:
I love the control of this rubber.
The balance between speed and spin is really good.
Way more control than Stiga Boost XT making my game slower but more consistant.
Value:
Great value for your money.
