It just seems clay courts were made for 2HBH players. Evert and Borg hold the record for most French Open titles. Nadal has won 77 straight on clay. The last 4 Americans to win the French (Agassi, Courier, Chang, S. Williams) are/were 2HBH. I'm thinking the 2HBH is better at returning high balls and taking the ball on the rise. 1HBH has less room for error and unless you have a lot of variety on that shot, you can't really punish people with it on clay. Federer is my favorite player and I root for him against Nadal. I just have to tip my hat to the clay master 2HBH Nadal, yet again.
