I have used 38-41 deg Commercial Hurricane 3 NEO. The harder sponge, the more possibility you have to make it harder for your opponent. But it demands more from your skill and speed as well. Recently I bought a 729 Battle II Provincial, 40deg. After four sessions and a competition I can say that this is a bit of a favorite rubber right now. Never thought a 729 rubber could compete with the best from DHS, but this one is really nice. About 8€ more than H3N, but more control and the same spin, just a bit heavier. Buy from Aliexpress, Ali Battleship has always worked fine for me. Rubbers used with a Yinhe MC-4 carbon blade...
