guys,maybe u dont remember how Pete used to serve in his best seasons..he was unbelaivable,specially at Wimbledon.dont jugde Pete's serve based on last 2 years performances,but based on his whole career.there is no doubt,he got the best one!
Goran´s serve is the best effective one WHEN it works. As it is not very reliable, since he can get 20947183569235 aces in a row AS WELL AS that many double faults in a row, overall I cant say he has the best one.
Taylor Dent has LOADS of power, and is a POTENTIAL best server. But he is not consistent enough yet to make it a reliable weapon.
And I must agree with Lindsayfan and Daniel, Petes serve is great. Maybe you didnt see it when it was effective, but it was a major weapon. And a plus, it used to ALWAYS work.
Krajicek´s motion is great, and Rafter has the most beautiful serve.
Overall, I still get Sampras, since he is the one who had it working for longer, who won a lot of matches on that weapon, and had it consistently at his serve. Serving is not only blasting, it is mental preparation and a matter of picking the right choice. Pete did all that.
I'd say Greg Rusedski, not also does he just have the fastest serve but his new serve compared to his last one has a lower ball toss so it makes it harder to read and he has good variation to it. And he can put great angle onto it and can do alot with the ball like topspin and slice.
