It's been a long time since I've done MMA betting. But back when I did my best hits were $50 on Matt Brown to best Jordan Mein by KO/TKO at +1000 and $20 on Pat Healy to sub Jim Miller at something like +2000 (don't remember the exact odds), the fight record is no contest now cuz Healy popped for weed lol but he hit an RNC. Back then there were a lot of prop bets that had odds that were way off, I deposited $150 initially on 5d right out of college and built it up to $2k after quite a while. Had to stop because I was spending way too much time watching all kinds of fight tape for cards, checking on line movements, etc... I was doing it while at work and got in the way of my productiveness big time.
