Your best bets for the odds:
Gemologist at 6-1: of the favorites, he's my favorite
Daddy Nose Best at 15-1: he's a closer and coming from a track that's produced Derby Winners in the past
Hansen at 10-1 and Trinniberg at 50-1: both are big time front-running speed, and although they're likely to jump out in front and then fail (particularly Trinniberg) we've seen wire-to-wire winners before.
If it turns out this is going to be a muddy track, throw some coin down on El Padrino at 20-1.
If you're playing a Trifecta, I think your best horses are Gemologist, Daddy Nose Best, and Dullahan. For a superfecta, go ahead and throw Union Rags in there.
Personally, I'm taking the four horses above along with Dullahan to win, then throwing a trifecta box out there with Gem, Daddy, Dullahan, Hansen, and Union Rags. Good luck to all. Please buy me something nice or at least some White Castle when you win the big bucks. Here are some good pictures for no good reason:
