Which WR's to start?

This is a PPR league and I need to start 3.

Currently I have these 3 in the lineup right now:

Marques Colston @ SF

Chad Ochocinco vs Baltimore

Steve Smith(Car) vs Tampa Bay

I like those 3 but I also love Santana Moss and his matchup at home against Houston. The Texans got torched through the air last week against the Colts and I like McNabb to have a good game as well. My problem with Moss has always been his inconsistency so I currently have those 3 starting right now. This has been a week long debate between which 3 of those 4 to start and I'm still undecided.

Thanks for any advice.

i like what you have in your lineup

start moss over Steve Smith
