Of course most people do not have the talent to achieve that.
Not exactly. Actually Andy's serve is unique. He use a "leg pump" push off to generate all that pace. Record a match of his and you'll see he spends less time in the leg bent position then anyone else on tour. Plus of course he has tremendous racquet acceleration. But otherwise your right all good serves hit it the same.
Roddick's serve isn't a thing of beauty, it's a thing of dominance.
