PLO8 vs O8

Have been playing low-limit Omaha Hi-Lo pretty successfully over the past couple of days. But when I try pot-limit, I lose money. Does anyone have any tips for making the transition?

Here's one, which I'm sure you already know: If you're going to stay in with a nut flush or nut low draw, it's going to more than likely cost you a lot more money to see all the cards than in limit.

PL O/8, however, allows for more scoop takedowns of pots with low hands and draw heavy boards - if you're winning in limit, why bother playing PL?

I suppose that's a bit like asking why all the fuss about NL hold'em when limit's out there... I just want to try to master the various games and develop my poker skills. Pot or no-limit games I think are generally more exciting and interesting to play.
