As a fellow tennis fan born way too late, I was unfortunate to miss out on a lot on good tennis rivalries. With the recent defeat of Federer against Nadal and threads about whether or not Sampras would be able to defeat Nadal, I was wondering how much the surfaces have really changed the past decade (the only one I have watched). My questions to those who have seen tennis evolve throughout the years: have the surfaces really slowed down that much? What about the ball bounce, is it true that, in general, the balls bounce up a lot higher than they used to? If so, do you think this evolution will stop and fast, low bouncing courts will return? (Basically, has this ever happened before?) Having seen highlights of edberg matches, I just wish I could be a spectator in a serve and volley era!
