We have a kid at the club, ~13 years old. He's a promising player, probably not pro material, but very good for his age (adult 3.5 rating on a good day). He is playing a lot, and his dad is putting him through tennis camps and tennis lessons (to at least get him to play tennis in college). I talked to him the other day about his string setup, and he told me he uses Black Widow, strung close to 60lbs, and restringing his racket every 4-6 months. Now, I know his dad and coach pretty well, and I don't think money is a problem, and the coach is pretty decent, so I don't understand why they are letting him do this. Isn't this an injury waiting to happen? I am thinking of talking to the coach/dad about this. Any suggestion on how you'd approach this issue? What would you say? I am not a string expert, obviously, and I can't pretend to be one, but I've done a lot of research, so I think I am knowledgeable enough to at least offer my opinion. BTW, he's using Dunlop Biometric 500 racket (forget if it's the tour version or not).
