I like the idea behind this system but seems like it would be hard to keep making a profit in the long run unless you keep avoiding sweeps. As an example if you hit your first 6 series all on the first game and go up 6U or so...if that 7th series is a sweep you lose 7U and then all your profits go away. It's great if you can keep avoiding sweeps but my only point is it doesn't take very many to make your profits disappear quickly.
This is partly true you just have to have the bankroll and the balls to make it work.
