Maybe an stupid question, because is almost always true the saying that is not the fish pole but the fisherman, but I wonder if the latest iterations of Head racquets, with its molecular technology have something to do with being at the top player's hands but Nadal these days. Just to name a few: Nole, Murray, Soderling, Gasquet, Cilic, Sharapova... Hmm, I wonder if there is some secret inside the racquets.
Pure marketing bucks. That's it. Simple business tactics. I'm not knocking them, they make decent rackets, but I'm sticking with my Dunlop 4d 100's (which no pros "use") because its the best fit for ME. That's the key. Don't use it because a pro does, find a stick that fits your game.
