Kvitova or Kanepi

Which girl will pose the least resistance to Serena? What about Pironkova or Zvonareva?

Kanepi, Pironkova.

Serena struggles agiant left handers, i would say Kvitova would be a real challenge for her

Kvitovas screams like a virgin after every error of Kanepi. Really annoying...

Both are headcases and "chocking"!!!
