Tourneys in omaha are in general a bit weird because the equitys run so close. If I considered play Omaha tourney's, I would only do it in a deep stack setting. The deeper you get, the more edge you can get with your skill, low stacks, it's like a slot machine almost. Not quite, but, I can't force as big of edge with omaha as no limit short stacked. The chances of me playing a short stacked omaha tourney are about 0%. I don't get the appeal.
