Here is the situation: Currently my son is ranked No.1 at our tennis club. He currently uses a Fisher racquet that weights 10.6 oz strung. Now, he has a powerfull forhand and 2 hands backhand. He loves to hit with a lot of spin. His pro says that is tiem to change racquets, something more heavy since he has a lot of power. We were looking at racquts specs and we came out with the following choices: 1. Yonex RDX-300 2. Yonex RDS-003 3. Babolat AeroPro Drive (i think is to heavy) 4. Head Flexpoint Radical Now, weight of these racquets are between 11.0 and 11.1 oz except the Babolat that has 11.3 oz. Head size 98 -100. Head lights. Can you give me an advice which racquet that he should use? I am a current user of Yonex rdx 500 (3) and just bought rds 001 (2). I love Yonex racquets but i am not the one who is going to use the racquet eventhough I know how my son tennis shots are very suitable for Yonex frames. Thanks in advance.
