What was it like? I'm fascinated to understand the difference between good club players and world ranked players!
As I said in the Exmouth thread the main difference would be the pace at which they hit the ball. Serves are a lot harder, groundstrokes have a lot more pace on them, and so much more consistancy as well which means you can't just get the ball back and wait for them to miss... if you play like that you have to get the ball back with either loads of depth of loads of spin to avoid being hit off the court
