PLO is way way eaisier than NLHE imo.
Most players (at 5c10c) have no idea what they are doing and call you down with top pair. Ive been killing the omaha cash games lately and I've also won quite alot of $5 heads up sng's. I even took a shot at a $20 heads up sng and won.
Just wait for some good hands and 90% of the time you will get paid off.
