Playing Omaha Hi-Lo 8s or Better

[Uncle Ves]

I use to play Holdem for a number of years for a living. I visited AC for the first time in a couple of years and found the professional players that were playing Holdem during my time are now solely playing Omaha for a living stating that it is more predictable and rarely play Holdem. Is Omaha a better game and what will I have to do to learn Omaha.
