My buddy "ruup2it" was hitting with the TW demos this weekend. He was using the Blade 16x19 with Wilson Sensation strings. He normally breaks strings once or twice each session, so it didnt suprise me that he broke the demo strings. As he took a cut at a forehand, we heard a loud CRACK sound. At first, I though he had snapped the racket. But then I noticed, the ball flew backwards after his swing. In confusion, he looked at his racket. We all busted out laughing as we saw this big hole on the top of the frame. And the result is what you see in the picture.
