I think 95% of people have mains break before crosses, but for some reason my crosses are breaking first. I just started tennis last September, and I've been hitting with a wilson tour 90 currently strung with alu 16L/Nxt 16 (crosses). I've noticed that the crosses shift upwards towards the head of the racquet, and the mains don't shift at all, even though i'm hitting with topspin. I've included a picture to illustrate the point. Does anyone else have this problem? What can I do to correct it?
