Agreed. I don't care for the insane variance of the Ainsworth 10K's. The River Dragon 5K's and their variants are a different story. They are very predictable. You will most likely get drained for somewhere between 10% and 20%. I did another play yesterday where the drain was 14.4% on about 29K in action. Started at 4917, ended at 4994. I finished an $829 winner plus insured the place will keep sending me the room comp and freeplay.
