Well, letís admit it. Why do we some rec players change racquets? Mostly because we get bored and want to try new ones. Of course we canít say that to ourselves as well as others and say better reasons like how they are different in weight, head size, flex, etc. etc., and it makes it look like we care about racquets. And this getting bored doesnít have a limit, so we appear to keep caring about racquet.
But obviously pros donít do that. They donít seem to get bored with their racquets, although I have never been in their head. Yeah I guess they have better things to worry about than equipments like opponent, practice, diet, fitness, etc., etcÖ
