Fantasy Football Week 11 RB's, I need help!?

I can start 2 or 3, but I'd rather only start 2 because I am stacked at the WR position, so that flex spot will go to a WR. Right now I have Adrian Peterson, Jason Snelling, Tim Hightower, Justin Forsett, and I can also pick up Bernard Scott, Ladel Betts, or Jamal Lewis, what should I do? (Besides start Peterson)
