I tried the new Tihbar ITTF approve 40+ ball on Sunday. It basically feels like a slower easier game. Yes there is definitely less spin, but this is relative to the slower speed and results in a very similar arc and bounce to previous balls, just at a bit of a slower pace. The bounce seems more consistent, so easier to judge, and the ball doesn't skid at all as is the case sometimes with the existing ball. The lower spin makes it easier to return serve, and combined with the slower speed and more consistent bounce, counter hitting is definitely easier. I can see the ball resulting in lots more long attacking rallies.
As for defensive players I'm not sure. It should be easier for a defensive player to return the ball, but at the same time the slower speed and less spin makes it easier for the attacker, so it could be quite balanced and just result in longer rallies.
I quite liked it overall, think it's going to suit my attacking game and help me as I'm pretty poor at returning serve. If it makes the game easier it could help with popularity of the sport and be better to watch.
