When you get up to about $500, play the .05/.10 PLO games on
PokerStars while playing the NLHE games. You should actually come over to UB. There's more Omaha action. More people buying in for the full amount and 10-handed tables so you spend less around the table.
Pick up
Championship Omaha by Bob Ciaffone and
Play Poker Like the Pros (Hellmuth) if you haven't already. I suggest that you study those books in order. Ciaffone's book was easier to understand and Hellmuth gave me some great guidelines and moves to execute Ciaffone's fundamentals.
