Hello everyone, i've been playing tennis for two years now and until the past two months I had never broken my strings. The issue I am currently having is that within the last month I've broken 6 luxilon alu power strings @55. I usually play with my brother and we hit the ball VERY hard and with a lot of spin. He hits a little bit harder than me yet he does not break his strings at all. I am just curious why I'm breaking so many strings, upon a closer look of the past 3 strings i've broken it seems like the crosses are cutting into the mains, it is happening along the entire sweetspot of the racket not only where the strings popped. Is anybody having the same issue?
