2 RBs, 3 WRs and 1 Flex?

[JRM4833]

I generally hate starting a WR in my flex but have to at least consider it this week. Which 6?

AP (obvious)
Moreno
M. Bush
Austin (obvious)
Fitzgerald (obvious)
Bowe
M. Williams (TB)
Crayton

Leaning toward AP, Moreno, Bush, Austin, Fitz and Bowe. What do you think? Should I sit Bush for another WR? Or some other combo?
