Of course, I love if you rate Rafa's #1, but having seen both live, I agree, both were stunning. I saw JMDP play Juan Monaco on Armstrong at the USO, in very close seats. His FH was so hard and flat, it looked like it was going through the net, not over it, and I mean from very close. It was huge, and came on you very fast. Rafa's was so tricky and heavy, with the spin. You had more time to see it, but, as John McEnroe once said, after hitting with Rafa, (on clay, I think,) he said it made you feel like your arm was being ripped out of the socket. That was why it wore players down, and esp. the one-handed backhand, like Roger's. Also, it was impossible to gauge, with all the spin. You may remember in the early years that Rafa's balls often got called wrongly out, a bit early, because it looked like they were going out. Lines people got used to it, finally. I once sat behind the server at an exho between Rafa and JMDP, (coincidentally to this conversation,) and I saw Rafa's ball do the oddest thing: Just as it was heading about 6" beyond the sideline, it turned 45 degrees and dropped in. It was honestly the weirdest thing I've ever seen on a tennis court. I'd heard commies say to try to sit behind the server and see that happen live, and I did, just the once. And that was on a hard court. Imagine on clay!
