I like a wide variety of games:
Sit & Go's (Regular) - Turbo is higher variance in my opinion, either 6 or 9 handed.
MTT's (a different range of them):
Stars spreads a 3-handed Zoom NLH PKO which I've made a couple of deep runs in, modest profit.
PLO/PLO8 MTT's either 6-handed or Heads-up (especially PKO's), NLH (6 or 9 handed)
Cash Games: Zoom PLO mostly, sometimes some NLH thrown in.
Ring Games: PLO, PLO8, 5Card PLO/PLO8
