Reggie Bush or Pierre Thomas?

I am in a similar situation. I am in a 13-team league with a max of 6 RB's. I have 6, Pierre Thomas, Ahmad Bradshaw, Knowshown Moreno, LT, Peyton Hillis, and Jahvid Best and another guy dropped Reggie Bush last night to pick up a Monday night player. I obviously don't really NEED Reggie, but I have the 1st waiver and Bush is really tempting with Pierre's shady ankle. What to do, what to do...
