Borgata 80-160 Omaha8 Hand

[Jeffage]

So I'm in an 80-160 Hold Em game at Borgata that converts into a half and half game b/c a huge action player that is fueling the game demands it. I'm not comfortable enough with my Omaha game to play these stakes, but when I say it 6 or 7 to the flop, I figure I'll play tight and try to avoid trouble. Anyway, this hand comes up.

I have A [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/club.gif[/img]9 [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/diamond.gif[/img] in the BB. Folded to a very loose player (any 4 will do) who calls. Action guy who game is built around raises (SOP), couple coldcallers, SB folds, I call. Flop comes K-2-3, rainbow style giving me a pair and the nut low draw. I bet, loose player calls, action guy calls and the others fold surprisingly. The turn is an offsuit 7 giving me the lock on the low side. I bet, loose player raises, action player then makes it 3 bets (while he is very aggro I think he is quite strong here). One of them has to have A4 also right? And the other has to have me beat for high right? ARG. I really didn't even want this game to go half and half but didn't want to be lone dissenter. Would anyone 4-bet here to potentially drive out a better high hand in the middle...I mean, this guy is crazy here, but not blind. Would anyone fold? Well, I coldcalled. The rest of the turn and river is somewhat interesting also, but I'll save it for later. How off is my approach to this hand?
