I add something else, I think rubbers also depends on the blade you use. For example, the dhs 301 been a firmer blade it was less catapult with Rozena, however with my nittaku acoustic inner, been a softer wood it was to catapulty , so not linear in play. So far less control. Lot less gears.
However when I changed it to Razka 7 a firmer rubber , slightly slower rubber but far more control, far less catapult.
Also just bought Razka x, only 5 minute hit so far. I say slightly faster than Rozena and better control too. Matching rubber with blade is important and also affects the control aspect too.
