PL Omaha books....

[IaHawk]

I searched for some PL omaha books on amazon and came back with a few but instead of wasting my $$$ and getting them all, are there any that some of you would recommend? Here are some that i found...

Secrets of Professional Pot-Limit Omaha by Rolf Slotboom

How Good Is Your Pot-Limit Omaha by Stewart Reuben

Omaha Poker by Bob Ciaffone

Championship Omaha: Omaha High-Low, Omaha High and Pot-Limit Omaha by T. J. Cloutier and Tom McEvoy

Thanks in advance for any help.
