Geez Robb, this is the longest I've ever seen one of your posts get ignored.

I move up at 20 buyins, and put a stop loss in at three buyins.

I agree with both you and IOPQ. I think you should try moving up when you reach a reasonable number of buyins. However, if you keep having to drop down, well then raise your buy in requirement to something higher so you can gain the skills and confidence necessary to move up.

I'm sure Spoon's advice is good. I know I've read it and will eventually start following it.
