I don't think you can say the odds are against a MMA fighter. Sure, self defence people can win, but I think unless you get the first strike to vitals, or manage to kick the balls :P, the MMA fighter is just superior in all other aspects.
Power of Rotary, why don't you recommend Krav Maga? I always thought if I were to complement my MMA with anything it would be Krav Maga.
