Why do pros like Safin and Roddick use regular short Tourna Grip? 1. Safin needs to cover up the black sleeve of Prestige Classic. Tourna GRip XL would do that for him 2. For some reason, Roddick puts his grip up really high. I don't see how regular, not XL tournagrip would fit that high Does any one know why they use regular and not XL tournagrip?
