I just got this rubber today, it is a Chinese topsheet with a Japanese sponge. i took off my Nimbuses and pasted these on to my super fast Galaxy T-2 carbon. I did not expect it to be this good; it is much spinnier than the Nimbus and it has a lot more control. I usually look at the control and am like ya bullsh** whatever, but this one is amazing. I lost a considerable amount of speed compared to my nimbus but i gained a lot more consistency. My backhand loop goes in all the time and my forehand loop has uncontrollable topspin. My playing partner made like two balls in then it either hit the net or flew past the table because he could not control it like my Nimbus. A hard but very loud sponge is what I like but some people don't like hard sponges so ya, heads up. My serves are much spinnier now like everything else. If you play with tensor rubber and switch to this you will be amazed at how consistent you will become. Very light, very tacky, very spinny, not fast, lot of control, many gears, high throw angle.
