I appreciate the video footage. But there is no real footage of your backhand that would qualify you as having a backhand to comment in that thread.
As far as betting with you, you are still being ridiculous.
I showed video of someone looping much faster than Timo Boll with H3. But you are likely correct in assuming Can's FH rubber is boosted.
All I can tell you is, it is possible. But the idea that you want to make a bet.....it makes me wonder about you. Sorry....the stuff you write about equipment, the ideas you come up with that seem to assume that everyone is the same and everyone will feel equipment the same way....there are a lot of things that I find strange.....but this, this is aggressive foolishness. I never said I would bet about anything.
But, I would love to see you post some footage of you looping backspin in a match with your BH instead of pushing long pushes with it.
In that thread where TaiHaoPingPong asked advice from players with good BHs you said:
I am assuming this advice is theoretical because in the video you just posted, you are always pretty upright and your head is an awful lot higher than the ball or your racket on all of your shots (except the smash of the popped up ball), particularly the 2 BH shots in the video. But I would love to see footage of you looping backspin with your BH in a match situation.
It is not hard to do. And it would be good to work on.
