I hold the belief that the racquet can ultimately have a difference in the game if you are comparing extremely outdated racquets to modern ones. For instance, I don't think it would matter to a pro which brand of racquet they were to play right now, they would still play amazing, but I think using a wooden racquet might affect their game, not by much, but definitely tell a difference. I don't think that I, personally, am good enough to be able to tell whether one racquet plays differently from another. I think the most important things affecting my game, equipment-wise, are probably my shoes and my string tension. Doens't even really matter to me what string I am using, as long as it is strung at a good tension. but that's just my opinion
Hope is not a strategy.
