I play cash and had a roll for 100nl years ago. I largely feel the same way, my current BR system comprises of 250 deposit for 10nl which is about as much of my own hard earned cash I can deposit without feeling sick. Idea is grind 10 stacks, take shot at 25nl, if I burn the 100$ I move down and repeat.

Perhaps you could use a similar idea applied to hu sngs. It means your going to move up fairly quickly without ever busting out. This way you don't risk too much of your own cash and you don't spend 100k hands in micros unless you suffer solid run bad.
