Does anyone have any suggestions for a racket for a 12 year old junior? Let me describe him: Rather short, Fast, All court capabillity, not wickedly strong. He needs something that's playable, not some super powerful killer. The racket needs to be graphite. I've tried a light full length, and you could see the wobble when he used it. Currently, he's getting a lot of torque from the metal frame he's using. Also I need prices. Thanks.
