Wells and Hightower vs NO. Start BOTH? WHIR

[diehardff]

So this is my RB sitch:

I can start 2 + a Flex RB

I have Jahvid Best (vs STL), Beanie Wells (vs NO), Tim Hightower (vs NO), Mike Tolbert (@ OAK), and Mike Bell (@ SF) on my roster.

Tolbert and Bell I picked up this week just to see if maybe they earned the starting spot this week, but I'll probably drop one or both before weeks end if I dont hear anything positive out of either.

Lurking on the Wire is Michael Bush (vs SD), Marion Barber (vs TEN), Chris Ivory (@ ARI), and Jonathan Stewart (vs CHI).

As of right now, I'm going Best, Wells, Hightower purely because NO is weak against the run so there is a chance they're both productive (no QB, WRs), and its really unpredictable who will out perform the other. Can anyone come up with something better than this? If not, should I go ahead and drop Tolbert and/or Bell for Barber or Bush?

Thanks for you help in advance, and as always, WHIR.
