Like the above poster, I think it's hard to overrate the importance of Roddick's 1st serve %. That, along with the effectiveness of his 2nd serve, makes his the one I'd want, even over Sampras's ad Karlovics, if I could have anyone's.
I know Dibley used to hold the record, but as you say the guy's from the medieval times. That's why I'm asking people to weigh in with what they know and have seen.
BTW the difference equipment makes in serve speed is negligible, for pros anyway. We're talking about 4-5 mph plus max with a proper technique.
And I just addressed your point about Roddick above.
