mixed games are far more profitable than nl holdem and a big reason for that is there is so much information and coverage on nl holdem that even the worst players have some knowledge on how to play, but if you play a lot of mixed games you will quickly see that the beginners are constantly putting their chips in drawing dead or at least drawing very slim. I recommend o8 as a game where if you study/play it for a while, it could reap you good profits in the end...
