i currently have a babolat aerostorm with babolat rpm blast. i want to have 2 or maybe 3 rackets but i dont know if i should get another one of the same one ive got or sell it and get a couple of lesser priced rackets. also i really like head, i dont know if that makes a difference though. i also dont want to be having to pay lots for restring or broken rackets. dont know what i should do. HELP!!!
