OK. I tried this in Max on a Yinhe V-14 PRO blade. I'm coming from having used almost only harder Chinese rubbers like DHS H3N 41deg, Yinhe Moon Pro Hard, 729 Battle II Prov Gold etc on forehand. Now trying this one. It's totally non-tacky. What hit me is that it's easy to make very good spin even on slower strokes, short services etc. Of course it's a bit springier than the Chinese rubbers, but not really by that much that I thought it should be. Short game and pushes are really nice. Further away from the table the feeling of control is total. The top sheet is quite soft and that gives a very controllable feeling whatever you want to do. This is no speed demon, but quite fast though. I have used Stiga DNA H 2.1mm as well, and R53 is a bit like DNA when looping, but I think R53 is a nicer rubber than DNA regarding control and spin. The effect isn't direct like when looping with Chinese rubbers, and the ball digs in to the top sheet more. That gives you a longer dwell time and more control in all game aspects.
