As for the two horses you mentioned, I like one and don't like the other. I like Crimson Hero to be a part of the trifecta at a big price. He ran 2nd in a huge key Allw race at GP. The winner came back to win the Withers, and the 3rd place horse just won the Lone Star Derby on Saturday. He ended up running 2nd or 3rd with a rough trip in the Lexington. At 20-1 he's very playable to hit the board. I don't like Booklet. At 20-1 I wouldn't talk you off him but at 10-1 I don't like him at all. He's a nice miler and he beat Harlan's Holiday twice as lone speed at 1 1/16 miles but the 2 times he tried him at 1 1/8 miles, HH kicked his butt. If he does clear War Emblem, he's probably going to be running too fast to last. The one chance he does have to win is if War Emblem has a problem coming out of the gate. If WE gets tangled or checked at the break, then Booklet could relax thru soft fractions; but I see that as about a 20-1 shot.
As for your question about who will be favored, I think Medaglio D'oro and War Emblem will be the top 2 betting choices, in that order.
