Totally agree Dust - Federer has been very injury free throughout his career due to his well balanced movement (as you mentioned).
I would have thought too re Rafa reaching Federer's 16, as he plays well on all surfaces - however the way he rips/grinds his body around the court, who knows.
Now with Djokovic stepping up to the next level, it sure makes for an interesting rivalry between the trio. Unfortunately, Murray still has issues and is coming back after a short break.
Talking about a great player on all surfaces, the legendary and cool Bjorn Borg - 6 French Opens (slowest surface) and 5 Wimbeldon's (fastest surface)
