i play wit ha guy who gets about 125 on his serves. we got ahold of a radar gun and timeed both of ours. thing is about his first serve, if you can guss where he is going to go, and he gives it away quite a bit, the way he drops his forarm and elbow when he goes down the T, you can get get your strings on the ball. its got a lot of kick on his second also, and if i just stand there, he can kick it at 90mph up to my eyes, and im 6 foot tall. on his second serves, i get myself moving forward, and i get abovce the ball before it jumps too high, this way you hit wiyth soem power, and you dont need to swing hard. i imagine its similar for pros, with the exception of roddick and a few others who are just scary as hell. If you guess right and learn from a few give aways they might let out, you can get to the ball. if you shorten up your swing and make sure the racquet face is pointed towards the other side of the court, you should be able to get soem returns back, quite a few with good depth adn pace. to answer the question, if i went up against a serve like roddicks, i doubt if icould do much better than scott or anyone else. but against more reaslistic players that we encounter in matches, try to use the ideas i presented, espcially trying to look for hints on the direction/spin of serves, and you will be better off.
