Joe B,
If you can, I would wait a bit to see an odds update today. I would sincerely doubt Caracortado goes off north of 15-1, let alone 25-1. Still offered 10-1ish at reputable offshore outlets.
Friday Preakness betting is completely different than Friday Derby betting. By end of the Oaks days, the odds quoted are relatively solid, and I believe represent fully commingled pools. Friday Preakness odds update only includes money bet on track at Pimlico and historically has had strange odds that change drastically by mid-day on Saturday.
The BES/Preakness double is a \"guide\" but that double includes more \"sharp money\" than \"tourist money\", so some things will change. For example, in the double, LAL was quite a bit shorter than Super Saver. My bet would be that they go off similar in the \"tourist money\" win pool, with perhaps Super Saver even favored. (although in this case, i believe the tourists will be right in that SS will run better than LAL, although I hope neither wins.....)
Good luck,
Jim
