I found my perfect combo more than 10 years ago. And I still use it. I feel no need to even look at the new rubbers or blades on the market, even with the celluloid ball. Besides there can be no replacement for my one-ply Hinoki Speed 90, and I just pair it with a tacky or semi-tacky rubber and it still has enough power to get the ball past most players. So pick a combo that works for you and then forget about switching. Proper technique will always beat a great setup without proper technique. We can all over-analyze if we let ourselves fall into that bottomless pit.
