whatdayaknow, yesterday had practice, the strings on my heavy racket broke, pickup my back up, a Hammer 6.3 (light racket. After practice my elbow and shoulder were hurting.
Now I need to go to the pro shop get my racket restrung.
Moral of the story, your back up racket should be THE SAME!
Anyway, I'll be getting those ISO grips, I hope they work out for me.
