I respectfully do not agree with
@Power Player's comment in that statement, if he is talking about TC97 16x19. I have flattish FH and OHBH, and the TC97 16x19 gives me significant amount of topspin, this was one area of my technique that had left a lot to desire and I was amazed how a racquet could help me with this issue. I have to admit that my topspin is not like
@Backhanded Compliment when he describes his shots as "high-kicking," but still so much that more of it is actually detrimental to my game.
With the TC97 18x20 had trouble generating topspin with my technique, I had to flatten my trajectory and preparation. It and I just could not get along, and I'll soon be selling it and sticking with my current TC97s. I think if you currently do not rely on topspin, the TC97 16x19 will help generate more of it, which may or may not be what you are looking for. If not, then the 18x20 maybe better suited IMHO.
