VEGAS Question

[FlBred]

I am going to Vegas in December. I am not much of a card player, but I do mess around with Roulette. My main thing is Horse and Sports betting so I will spend most of my time in the sportsbooks. My question:

What sportsbook has the best reward program and will comp me the best. I am not a HUGE player, probably $50-100 per game and $25-50 per race. I will be traveling there more frequently now and it would nice to get some comps eventually, thanks for your help!
