Need Lineup Help

Second straight week I can't figure out where to go with WR2, RB2 and my flex.

I still won my matchup last week, but I left plenty of point on my bench.

12 team .5 PPR

Locked in I have

WR:
Dez
?

RB:
Murray
?

Flex:
Wallace - for now


So I have these options to choose from:
WR/Flex- Vincent Jackson @ Pitt
WR/Flex - Kelvin Benjamin @ Bal
WR/Flex - Mike Wallace @ Oak - Game is in London
RB/Flex - Frank Gore vs Phi
RB/Flex - Reggie Bush @ NYJ
RB/Flex - Stevan Ridley @ KC
RB/Flex - Ivory vs Det

I'm leaning toward Wallace being a must start. I'm also to the point where I'm tired of Vjax putting up duds, where as Benjamin has been a consistent play. However, I feel like the second I take Jackson out of the lineup he will go off + Glennon is finally starting.

At RB Gore let me down last week, and I constantly hear about Hyde taking over. Bush is playing a stout defense, but should get more opportunities than Bell in this matchup. I don't care for Ivory vs Detroit, but he's been solid. Ridley is boom or bust IMO.


What do you guys think?
