I'm seriously considering adding either a Yonex RDX-500 and/or a Yonex Ti-80 to my line-up. Currently, I'm using Babolat raquets. As far as I understand, Babolat raquet grip sizes are a half a size larger than "standard" (whatever that is) and Yonex raquets are half a size smaller. I like Babolats in size 3; does this mean I should a get a Yonex in size 4? I think that's what I should do, but would appreciate if those of you, who have used both brands, can confirm this to me. Thanks. TW: PLEASE give me your opinion, since the Yonex raquet/s will be ordered from you and I can't demo from where I'm at.
