Too light and stability issues. I was playing with the OS. When I started playing against faster pace, even on cleanly struck balls the racket would be twisting in my hand. Returns especially and my returns are the pride of my game. It might just be personal preference however. I think they're good tweener rackets, but they just weren't for me.
