perfmode, watever, let me clarify. Logically speaking, lighter is easier. Never said that heavy racquets werent bad, or dat dey didnt use dem. It might be good to have a hevier racquet, but not too heavy............
Well, I think 14oz weights is a little too heavy for optimal play in today's quick game, though sampras did but that's more an exception. I think phillipoussis plays with a 14oz stick too but look at the size of that guy. Most pros I would guess play in the 12.5-13 ounce range. If you ever try to return a big serve with heavy spin using a sub 11oz racquet you will begin to see why a certain amount of mass is needed.
