Eli or Jay Cutler this week?

Eli Manning against the Redskins or Jay Cutler against the Lions? I have Kevin Boss as TE (Vernon Davis on Bench), Manningham and Andre Johnson as receiver, Jammal Charles and Mike Goodson as RB, Steelers D (Rams D on Bench) and Mason Crosby as Kicker ( Tynes on Bench). Do you guys recommend starting percy harvin or fred jackson as flex? or maybe even starting jackson over goodson and leaving harvin in?...what do yall think?
