I actually like Omaha H/L. If you play it long enough, you can tell which hands will almost guarantee you some of the pot.
Only thing I don't like is people that don't know how to play it and think you should bet like in Holdem. Since the chance of splitting a pot with someone else is high, then you don't want to push people out with over betting. With the split pot structure, you want to keep as many people in with a winning hand as possible. Otherwise I have split way to many pots with just me and another player who pushed everyone else out. Ticks me off. The Omaha and Omaha H/L book from TJ Cloutier is excxellent.
