Omaha information/books, question about specific books

[TIGERsrm]

I have decided to learn PLO since I play poker full time and it would be good to branch out from just playing hold'em. Learning a new game is always fun too, plus I get to be a donk all over again [img]/images/graemlins/smile.gif[/img]. Hopefuly not for too long though!

Just ordered "Omaha Poker" and Slotboom's book. What about Stewart Reuben's book "How good is your PLO", any good? Is it targeted more for beginners or advanced players?
