I would love to play against someone who plays the modern game. As is, I've never seen topspin come at me. I've never seen a kick serve. Never seen a serve jump over my head. I've only seen extreme underspin. At the San Francisco Open, there were two guys that put noticable topspin. Everyone else hit flat.
What I see a lot of is people using AeroPro strung with polyester hitting flat.
That's not the case where I live/play, I play a power top spin game (not consider myself an open level player), I break strings (black code 1.30) each three sets. I've lost to some proficient flat hitters, but chances are they won't be able to handle the weight of my ball, what I happen to prefer are dense string patterns sticks, 16x19 are too lively to me, and because of my full western forerhand grip I hit with top spin even with the cover on
