Not all future bets are through the pari-mutuel pools (I think Covello found Archarcharch at 250-1 in Vegas earlier this year). They briefly had BC parimutuels, no more.
The ones I hit were Sunny\'s Halo at 30-1 before the Arkansas Derby (he went off favored in the Derby), Funny Cide at 93-1 (first pool, only ticket I cashed on the Derby that year but good enough), War Emblem as part of the field in the second pool (7-1 I think, but I had something like 15 horses covered between the field and two other future bets), and the Mandella horse who won the Classic at SA (I had him @ 50-1, didn\'t use him in the race, forgot I even had the bet until after the race). Don\'t play them every year (didn\'t this year), there have been plenty of losers, but ahead pretty good overall.
