Right now I would go:

Street Sense
Great Hunter
Scat Daddy
Notional
Any Given Saturday
Nobiz

in that order.

Circular Quay I dont like at all. If he does win, preps are really going to change. Barbaro has started a trend that might die this year. If CQ wins, huge reinforcement of take it easy path.

If Scat Daddy wins, more of a return to "run that animal". Very trendy stuff.
And I also realize the trendy nature of my first two as they will run tomorrow. They have not hurt me yet. So we wait. WE also must make note of post position influence. If Street Sense starts from the 20 hole... I dont like him.
