My sister is in college right now and play every day...so she breaks racquets like every week, and we don't want to buy her $7 every week and $5 for someone to string it. The best string that her coach can get is Prince Pro. He said a lot of the guys use a hybrid of this with synthetic gut (like the Blend that you can buy from TW). She's gotten used to Head Fiber gel Power 16g, would this be a good/safe move for her? Also how well does kevlar play? i don't see very much on the market. I'd like to tell her what she should try out. Also is there any other Prince string that you'd suggest that would be better than this?
