Played some in a big game

I played some in a big game. They had a mixed game and a pure holdem game. I played holdem, since I am pretty much lost with these guys in omaha. I won't say too much about the game, other than pretty much all of the best cash game players in town were there. There were a couple of live players, but they were playing the mixed game. I ended up winning, but only because I flopped a set against a guy with KK. I plan to play again, but will stay clear of the mixed game. I feel like I can play holdem at this level, but am the sucker at the mixed game.
