I don't either think that spin reversal is the answer, by dynamics in germs of speed and placement might be it. When I look at 18 year old Frictionless anti-player of Luxembourg Ademir Balaban in this game, it is clear that he uses a fast tempo with many twiddles and direction changes to get his opponent off balance. After a couple of sets his opponent is more adapted to the game and you can see clear patterns, but still he finds no way out of Ademirs chains, he is trapped. A very interesting and modern way to use a less grippy rubber. Notice how Ademir turns his bat almost upside down to be able to use FH rubber on BH side without twiddeling:
