Peyton Hillis or Tim Hightower? or kevin walter? or louis murphy?

with peyton hillis' recent production and Beanie wells' return I'm very tempted to finally start Peyton hillis in my W/R position (i would have won last week if I did so but who know he would do what he did in baltimore??) i already have Deangelo williams and cedric benson as my two starting running backs and Moss, H. Nicks, and mark clayton as my wide receivers. i also have kevin walter and louis murphy on the bench right now so i can put them in too for hightower (andre johnson might not play and murphy has a good matchup against the texans). damn i hope i don't go 0-4...
