Books on Omaha Hi

Hello,

I'd like to know, which Omaha Hi books are worth to read? I am considering buying Cloutier / McEvoy Championship Omaha. Are there any other Omaha hi books?

I am also thinking of buying Zee's Stud Hi/lo / Omaha Hi/lo book, are there any other books I should consider?

Ciaffone's Omaha Holdem Poker book. It's slim, but covers Omahi high, and a little PLO and O8. I found it helpful to better understand Zee's O8 book as well as Ciaffone's pot limit book. Get it.

Not that I've played a lot of high-only Omaha, but Ciaffone's book is pretty good. Ray's book should be all you ever need to beat most Omaha and stud/8 games.

Ciaffone's Omaha book is the one to get. Apart from the fact that the content is excellent, Ciaffone is up there with Andy Glazier in terms of writing ability.
