Yes,all different 4 surfaces.USA Open(Hard),French(Clay),Wimbledon(Grass) and Australian Open(Special Synthetic,they have changed to hard courts now)

Sampras,A master volleyer,could not overwhelm Federer in their only meeting.And mind you,Federer was no where near his current form then.You will agree with me that Roddick's volleying skills have improved a lot under Connors,yet he is passed repeatedly by Federer and of course,Nadal.If you remember Roddick's lamentations after he lost to Federer in the US Open 2006,he said,and I quote:"If I come to the net,he passes me,if I stay at the baseline,he passes me.I just feel like giving him a punch"That tells you the level of frustration,even for a player of Roddick's status.Stefan Edberg,I agree with you is arguably the best volleyer in open era tennis,but as I said earlier,racquet tecnology has changed things a lot.Receivers can attack any serve now with pin point accurate returns behind the on rushing server.That's the changing face of the game.And dont forget also that the courts are also being gradually changed to slower courts.I was at the Wimbledon(live) this year and the grass courts,are actually a bit slower now than previously.I think it has something to do with the specie of grass they are using now.So all these make baseline play attractive for players.Net play comes in handy only when you have your opponent pinned.

Yeah I agree,double fisted backhand,taking the ball early is a clear advantage but it also has its limitations,regarding reach.Agassi was really great,no doubts and I admire him a lot.As for Federer and Nadal's high bouncing spins,I will comment on that later as I have to go now.

I agree intoto with Octupus.I believe she must be a tennis player and an ardent follower of the game.

Hmmmm. Interesting discourse by u all.
