Tough to say. In the past few years the vast majority of all tournaments have been No-Limit Hold'em, limiting our sample size for evaluating the most likely-to-win rounders.
This list isn't an attempt at a definitive "best of the best" O8 players; rather, it's a roundup of those I think have the best shot at winning this particular WSOP event.
5) Ted Forrest. Coming in at No. 5 is Ted Forrest. He was No. 3 on my Stud list, so it's not surprising he shows up here as well.
With the majority of the world being Hold'em specialists, the players who play one alternate game at a world-class level are usually the same ones who excel at the other non-HE variations.
Forrest's most recent cash was second place in Event 16, $2,000 Omaha Hi-Lo Split Eight-or-Better, at the 2008 WSOP. He's one of the world's best poker players, with an almost unmatched skill level for O8.
4) "Miami" John Cernuto. Miami John also made my Stud list. His record for Omaha Split games is almost as impressive as his Stud record, with 65 O8 tournament cashes and 11 of those wins. In 2004 he was a runner-up for a WSOP O8 bracelet.
On top of his tournament results, he also has the respect and support of many of the other top players. Just like Ted Forrest, his most recent cash was also in this year's Event 16, Omaha Eight-or-Better.
3) Mike Matusow. With three bracelets - one of them from a 2002 Omaha O8 event - Mike makes this list with ease. He has over $6.2 million in tournament winnings and he's just coming off a 2008 WSOP bracelet win, which can only boost his confidence even further.
The No. 1 reason Matusow makes this list is that he truly believes that the Championship O8 event is his for the taking. He is focusing all of his energy on that one event, and plans to do nothing less than take it down.
His dedication to this single event is unparalleled, and might give him the edge he needs. Not only does he have a bracelet win in the genre, but he finished runner-up in the 1997 O8 event to my No. 2 choice ...
2) Scotty Nguyen. Scotty Nguyen has over $7.4 million in tournament winnings. He has cashed in 32 Omaha Hi-Lo events, nine times in first place.
Two of his three WSOP bracelets are in Omaha Hi-Lo events, his third having come in Omaha Hi. He's widely viewed as one of the top O8 players in the world, and without a doubt has a solid chance at taking it home.
1) Scott Clements. Clements' name is far less familiar than those of the other players on this list, but there is a good chance that will not be the case for long.
He has over $3 million in tournament wins, and won his second WSOP bracelet in a 2007 Pot-Limit Omaha Hi event, with his first in 2006 for Championship Omaha Hi-Lo. And he's won many large Hold'em events, proving to everyone that he can go the distance in large fields and finish on final tables.
The reason Scott gets my top slot is for his latest impressive feat - cashing in all three of the 2008 WSOP events to have featured Omaha Hi-Lo Split so far, including making the final tables of Event 6 and Event 16, both exclusively Omaha O8.
Event 10, an Omaha/Seven-Card Stud Hi-Lo event, saw him reach the money in 39th place overall. That means he's three for three with a bracelet for the very event in question, so Scott Clements is my hands-down favorite to win.
