I am in a PPR League

We start:
RB
RB/WR
WR
WR

I have:
RB's
Frank Gore (SF) vs Den
Cedric Benson (Cin)vs Mia
Ricky Williams (Mia) @ Cin
Michael Bush (Oak) vs Sea

WR's
Brandon Marshall (Mia) @ Cin
Brandon Lloyd (Den) @ SF
Mike Sims-Walker (Jac) @ Dal
Braylon Edwards (NYJ) vs GB
Lee Evans (Buf) @ KC
Austin Collie (Ind) OUT

I am certain I am going to be starting Gore, Marshall and Lloyd. I am trying to decide to start Benson at Flex postion or go with one of the my WR's. Please Help!
