I hear this one of the best multifilaments out there. Since i am not a frequent string breaker i am up for anything. I havent had arm problems with my hybrid of xcel and pro hurricane in my apd but i think I would in an all poly string setup. My question: Would tecnifibre x-1 biphase be too powerful to put in an APDC or any babolat racquet(besides pure storm ltd.)? If so should I go with poly-multi hybrid?
