Fast Grass-Sampras or Pancho
Slow Grass-Nadal or Federer (Though I'm sure Laver would have his chances)
Clay-2008 Nadal or 1995 Muster (The two highest levels Ive ever seen on clay)
Fast Hardcourts-Sampras or Federer or Connors (I can't really choose between these three here.)
Indoors-Sampras, Federer or Becker
Agree to all, except slow grass. Sampras would still be the favorite over Nadal on any type of grass.
