Flex spot Help - Tolbert, James, or Ochocinco, WHIR

[mgoose]

QB Ben Roethlisberger
WR1 Miles Austin
WR 2 Pierre Garcon
WR3 Patrick Crayton
RB1 Adrian Peterson
RB2 Peyton Hillis
TE Jacob Tamme
Flex ??????
So that's my team, I started Crayton ahead of Ochocince because of the matchup, I have realistic options for my flex

1. Mike Tolbert - losing time to both Matthews and Sproles (whom I have also fwiw), but gets goal line touches.
2. Javarris James (Ind) - with Hart out he will split carries with Brown, and with Manning at QB you never know
3. Chad Ochocinco - been a bit of a disappointment this season, seems like 2nd target to TO, and tough matchup vs. Pit

Rest of my Bench
Gates
Torain
Forsett
Sproles
Gerhart
