If you were a Tennis Pro, and had a choice of which slam you could win. And that would be the only slam you would win, which slam would it be? Personally, in the History/Prestige category I would pick Wimbledon. In terms of electric atmosphere, number of spectators, glitz, glamour and pure adrenalin and excitement etc., Id have to say US Open.. by a mile. I have yet to see a more intimidating, imposing, electrifying arena than a packed capacity Arthur Ashe stadium, especially at night under the lights. It is absolutely amazing.
