True though
But the consistency of the Chinese is also something that we should take into consideration.
It works well with Harimoto because of his current passive playstyle?
My thoughts are like these pros are already fit and generating tons of power in their forehand swing, so zyre doesn't make sense there. But for backhand maybe it's a different story.
You sound like another poster here but I think you are much better informed. If we take your thoughts on power to the extreme, shouldn't pros be using the slowest equipment because of how much athleticism they have? It doesn't really work that way. H3 is an acquired taste and is for people who are used to the slower ball release and harder sponge. Do remember there was a time Dima tried H3 - didn't last more than a couple of months. And Dima is notorious for being one of the most powerful pros on the circuit.
Time/speed is always a factor at the highest levels and because threat/quality affects consistency (both for you and your opponent), consistency is never everything. Harimoto has been more aggressive with Zyre on his forehand and backhand than I remember previously, and for the obvious reason that even with his relatively slow blade, one shot can win the point more often now. Watching him against Peng, Peng looked really slow. And while Zhou Qihao looked better for sure, on some shots, Harimoto just put the ball past him, no questions asked.
I know a Nigeria pro (max was about 2600 USATT) who couldn't play his best game with 09c because over time, it made him injured because he was always looking for the speed - his results were much better with T05H. There are also top pros who will reject 09c out of habit (LYJ, Harimoto, Kanak, Togami etc.) because the slow ball quality doesn't fit their game. Quadri can't stand sticky rubbers, and he should fit your model, no? In fact, when I used 09c and Hurricane, my coach said that he wanted me to hit a faster ball and that my spin wasn't going to trouble good players but a faster ball likely would.
Even the Chinese have to deal with the tradeoffs inherent in using such rubbers (remember when Fan was struggling on those Tibhar tables against all those German League players) and it has never been really clear exactly what the properties of the H3 the top Chinese use is and how their boosting affects it. H3 ultimately is an acquired taste, if you used it as a child and got used to it and never found anything better, great. But I don't know many people who switch to it later in life and feel that it makes them much better, especially with this new ball that is incredibly hard to get moving. And because this ball is hard to get moving, Zyre appeals to a lot of players. The tradeoffs are real, but they are just tradeoffs.
