Is there any correlation between playing level and durability of string? I have a mate who claims to bring numerous racquets with him every time he plays because he hits so hard that he breaks string each session. I was like that a few years ago, but as my game has matured I've saved a lot of money on stringing. Over the years, I've learned to not bash the ball every time and I get many compliments on my consistency. I read a thread on here a while back which read that string breaking actually indicates that you are missing the sweet spot. Can I receive the whole truth about string breaking? BTW, I use thick gauge strings strung at high tensions, so that may be a difference between me and my friend.
