Forsett vs Pierce

I have both on my team. Standard league. I know all the experts are saying Forsett is the guy to play this week after last week's performance from both he and Pierce. But for whatever reason, I have a hunch that Pierce will be bounce back in a way. Anyone else feel the same way?

I'm playing against Forsett in one league where I don't have Pierce. He had first waiver priority and I had second. In my other league, I used my number 1 waiver priority on Forsett (I originally had both Rice and Pierce in that league and dropped Rice).

So ultimately, my dilemma is should I start Pierce in one league over Forsett, even though I'm playing against Forsett in another?

I know most will say Forsett, but I hate having to root for/root against the same player. Takes the enjoyment out of it IMO.
