I'm pretty sure no one will answer this, but I'm buying a racket and I was wondering which to buy. I was thinking of temporarily trying the Head liquidmetal 8, but I really want either Sharapova's or Jankovic's racket. I want a racket with good power and a larger sweet spot so I don't know. I think I might take a trial on the Sharapova racket, it sounds perfect in the description.
