I have never tested such a rubber before. Because of my age and on-going injuries, I wanted to slow down the game a little bit. I am currently using this rubber on my backhand. It is a learning curve for me, and this rubber is amazing. It does so many different things, if used correctly. My opponents are finding it difficult to return my blocks with it. It is short pimples but acts more like an anti rubber. The good thing is that you can flat hit with it without any issues.
