Top players hardly ever change their racquets. Constantly changing racquets will screw up your game. Us normal folk keep buying all the latest and greatest frames in search of the holy grail, when all that money would probably be better spent on a few more tennis lessons. We keep the big racquet manufacturers in business. The pros just go through numerous paint jobs reflecting the latest and greatest release while still using the frame they've been using for ten years. We should learn from this. I'm sadly one of the worst offenders. It's sad that I know this but continue buying and trading buying and trading. Sigh. My wife calls it a sickness. I agree. Of course if I we're getting a million dollar contract to switch to another racquet company that would be an entirely different story. We all can dream, eh?
