My99broke,

I think you need to buy cheaper racquets!

FYI, I had a racquet clash in doubles. My partner stole my shot (it was my forehand and he swung backhand). My partner was an ex-international player!!. His racquet exploded just like yours. His racquet was an ISO800. Mine a cab20. I think his was CN, just like mine.

I used cheaper Kennex racquets, when a student, all the time, until I started working. Dunno if you can source another brand to do the same thing.
