Hi, I'm a competitive 14 year old who currently plays with a pure drive, and I am looking at possibilities for my future racquet. Something maybe around 11.5 ounces, a bit less stiff than the pure drive (I think that's what I mean; around 68 I guess on the stiffness rating), standard length and playability not too different from the pure drive. A few new ones I have my eye on (some aren't out yet; I think they're due out in March): babolat pure drive roddick, yonex rds 001, wilson nblade (don't know much about that one) and head flexpoint prestige. Any thoughts? Thanks!
