I probe this rubber for about two months, the first impression was than this rubber is the most faster that i never had in my hands. For serve is cool but not the best, if you want to use a kill backspin, but when you play with an agressive player, you have a little advantage with your block, because this rubber can reverse the hit with good accuracy.

Sidespin and another hits are stronger, however you have to do all of the hits with perfect technique if you don't want to lose by not forced errors.
