Looking For Some Wager Guidance @ Belmont

[RollerDoc]

My history is I only bet 4 races a year (the TCs and BC). And I only pick a horse to win. My lifetime record is 7-4 including Big Brown ($200.00 to win) in the KD and Preakness. So I am up about $540 this year (obviously the lionshare won in KD).

My budget for The Belmont is $300. I am planning to bet 200.00 on Big Brown to Win only because I love the horse and it makes watching and cheering that much more of a rush for me. So I am not straying from my winning $200.00 format with BB.

What I am asking for help with is the additional $100 I have to wager. I know my payout on Big Brown will be minimal if he wins. Any suggestions what to do with the other $100?

I have replayed the KD several times and was impressed with Dennis of Cork's finish. I was feeling great about a bet on him across the board but learned his jockey will not be Borel, so now I don't know. I also like Tale of Ekati. I'm not sold on Casino Drive. Help!
