In or out?

[CletusVanDamme]

2/5 PLO8. All stacks in hand greater than $800. I limp EP with A [img]/images/graemlins/heart.gif[/img]2 [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/diamond.gif[/img]J [img]/images/graemlins/spade.gif[/img]. Several other limpers.
Flop is 4 [img]/images/graemlins/club.gif[/img]5 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/club.gif[/img]. SB, and very loose, slightly aggressive and mediocre plays pots for $30. UTG, and slightly loose, pretty decent player calls, after mumbling something about "I'm not gettting all of this pot". This could mean several things from him. Most likely, though he is being honest.
I really think I should have just folded on the flop, but with several passive players behind me, I though a raise was unlikely, and we might get some stragglers.
Turn is 3 [img]/images/graemlins/club.gif[/img]. SB bets $200, UTG calls. My thinking is at best, I'm getting half. At worst, I guess 1/4. But of course, the wheel is no good for the high here. And, considering than in addition to the $200, I'm most likely facing another $350+ on the river, I decide to fold with only $35 invested in the pot.
Now, hindsight being what it is, neither player had a wheel, or even a chance of one on the river. Both had flushes with weak lows.
Do you think this turn bet is a call I should be making? Pros: I have a wheel. One player in pot isn't that good. Cons: Someone definately has flush, and I feel it is quite possible I'm getting quartered, and will have to put $600 in pot.
