I string out of my house. Today I received a racquet and did not realize it had a crack in it when I got it from the customer. As I was removing the old strings I notice a crack in the frame at the PWS. I know if it breaks while stringing it I owe the guy a frame, but in this case I caught it early. Should I offer to compensate him? If so, how? The racquet is no longer made, so how do I value the compensation? thanks guys in advance for your advice.
