I have never played fixed limit omaha but it seems to me to be similar to having a fat woman doing elbow drops to my nuts for a couple hours.

Yes, while at the low stakes the pot-sized bets don't do any good, that's still a GOOD THING:

You flop top set, for example, and they chase to the river. Well, sometimes they make the flush, but only 1/3 of the time. If they make it and the board pairs, you stack them. If they make it on the turn and pot it, you just lay down. If they make it on the river, you lay down. So, while you by no means always win here, you can create some very good EV situations in pot limit.

Just let 'em chase against the odds...

In any form of poker players calling without odds makes you money. Fixed limit, NL, pot limit, draw. Any time someone is caling with hands that arent getting the correct odds your EV goes up. The best trick to small limit PLO is to let everyone else make the mistakes when you have big hands. Lots of players cant fold bottom or middle set, when they get raised and this can make you a lot of money in what is usually a very low risk hand. A couple of small things to consider. Avoid drawing to anything but the nut flush, drawing to little flushs will kill you. Be carefull with bookend open ended draws on boards with big cards. For example J8 on a 910X board. It is really easy to be up against JQKx since big wrap are really strong in PLO. These "open enders" really are gutshots since the only safe card is a 7. The best way to make money in low limit PLO is very much like NL, play tight and let other peoples mistakes pay you off.

Also being able to lay hands down plays a BIG factor in PLO i've found.
