Hello guys, I have a Dunlop Bio 500 tour. I am looking for a racket with more control for volleys and winners, while the top spin in groundstroke. I think the Yonex Ezone _ai_98, Vcore_Si_98, Wilnson Blade 98 16x19 or New W blade 18x20. Would a good choice or am I doing stupid things? Decided the racketes which strings and tension suggest me?
