Bent or Keane vs QPR? Price makes no difference and whichever I go for will be shipped out after one game. Thoughts?

I've gone for Keane and I have the exact same thing, I'll be bringing in Ba after this GW (is that your plan too?:))

Reason - If Bent doesn't score he probably won't do anything else. Keane may also assist and will probably be more likely to take a free-kick, then again Bent is on Pens.
