Due to some issues with Talk Tennis Account, I wasn't able to create this thread right when I saw the cracks, which was 2 days after I have received the demo. I didn't check the racquet when I first received it, so I don't know if the cracks were on the racquet before or after I got it. The demo was Wilson Prostaff 6.0 85, strung with Luxilon Big Banger Alu Power (gauge and tension unknown). The first crack seem to be just a paint crack, but the second crack looks serious. Here are some pictures: [/IMG] Side question: Does anyone knows the tension that the demo was strung with ?
