Waiver pick dillemma: Should I pick up davone bess, Danny Woodhead, or Tony Moeaki?

Davone Bess looks like a obvious #2 guy for Henne. That Danny Woodhead guy is small but quiiickk! but he will also be sharing targets with the likes of Wes Welker, Brandon Tate, and Tony Gonzalez....and Tony Moeaki and Cell might have something going on like Rivers and Antonio Gates but the future is still unclear...I can only pick two of those three but its really hard to choose... Any Thoughts my fellow FF experts?
