Allright. This rubber pretty much rocks. The price is pretty reasonable for how good it is. The topsheet is simply amazing. You get great spin and a ton of control. I feel like I can loop anything with this rubber. The sponge is the one drawback to it. The sponge could be better. But the sponge is not bad. It just is not as good as it could be. And the topsheet is so good it makes up for that. This rubber was made for the 40+ Poly ball. It works great with either the celluloid or the poly ball. But it really grabs the poly ball quite well. The throw angle on this rubber is medium high. But you get a great arc on the ball because of how much spin this rubber can generate.
And this is one of the most durable rubbers I have used. Even with this rubber looks dead and worn out, it still grabs the ball well enough to keep using it.
