Also the slowing down of the game in general, by slowing court surfaces and increasing the size or weight of the tennis balls has pretty much given the baseliner the advantage over the S & V.
I think so. Mud slow court speed and "reportedly" slightly bigger and heavier ball
(Roddick refered them as watermellon ball AFAIK and Henman's "claim" that
Wimbledon opens the can of balls well before the start of tournament)
I'm surprised lots of people do not know or care. IMHO, it changed
the whole game (not a sudden change, gradual changes over many years).
And the new generation polyester happens to be better string for current baseline
oriented game...
