Started playing last summer and purchased a Prince o3 red at 10.5 ounces and 105 sq.in. As I improved, the racquet began to feel too light, powerful, and have limited potential for control. I don't have access to many demo racquets so I've been trying to play around with the weight to find a weight and balance that fits my natural swing better. Used lead tape and quarters under the handle to recreate the weight and balance of more control oriented racquets to help narrow down which ones would be good to demo. Is there an upper limit to how much weight you can add while maintaining racquet performance? Could I chance my racquet from 10.5oz and 3pts HL to something like 12.5oz and 8pts HL and it still be playable? Or if I want one that's 12.5 and 8, do I really have to get one that comes factory made like that?
