I've ordered a couple demos, but I'm just curious as to what you all think about the differences/similarities between various Yonex models in terms of control/spin/power. The ones I'm looking at are: -RDiS 200 -RQiS Tour (or XL 95 version) -V Core 98? (I know it's new, but from what I've read from a couple threads already, the vcore is similar to the RDiS 100 MP.) I've been hitting with the Pure Drive GT Roddick for the past year, but I'm just trying to find something a little more forgiving and control oriented. I don't have trouble with elbow/arm issues, in fact I usually prefer a stiffer frame which is why I might not like the RDiS 200, but well just have to wait and see. PLEASE share any knowledge/experiences!
