Benson and Forte for AP

This one team I have in a 10 team league is probably the best fantasy team that I have ever amassed in my 9 years of playing:

QBs: Big Ben, Cutler

RBs:
MJD (drafted him)
Gore (traded Best and Matthews for him)
Forte (drafted him)
Benson (traded Orton + Tolbert for him)

WRs:
Reggie Wayne (drafted 2nd round)
Roddie White (drafted 4th round. Incredible, I know)
Naane and Gaffney backups

TE:
Zach Miller

I'm undefeated and will almost certainly make the playoffs as everyone else in my division has at least 2 losses.

My reasoning:
Forte has a rough couple of matchups in the playoffs, the Patriots (19th against RBs) and Minnesota (5th against RBs). Benson plays Pitt (3rd against RBs). AP plays the Giants (26th against RB) and Chicago (15th against RB)

Gore plays Seattle and San Diego those weeks and MJD plays Oakland and the Colts.

I'm not going to start both Benson and Forte in the playoffs so I'd almost definitely get more total points because AP should score more than both of them, both weeks.

My only fear is that one of my big 3 RBs will go down during the season and then I'm screwed. I love having Benson and Forte simply because of the insurance.

Thoughts? I might wait until week 11 or so and then propose the trade. The guy who has AP is really weak at RB and would probably take that offer. He has AP, Michael Bush, and Tolbert.
