Who to start at RB Week 1? Slaton, Smith, or Bush?

I'm having a little trouble deciding on my RB for Week 1. I have to pick 2 and I've got Steve Slaton, Kevin Smith, and Reggie Bush. As of right now I'm thinking Slaton and Bush but I'm still not sure. I feel like I have to start Slaton, but I think all 3 should do well. Since Thomas is out, Bush should have a productive day and its a PPR league so I think he'll rack up points even more. But Smith is an every down back and had 111 yards rushing, 1 TD, 3 rec and 7 yards receiving least year against NO so I figure he'll get similar stats at least. Just looking for opinions. Thanks.
