This might be a situation where seting a loss limit is a good idea. Not necessarily on a particulart table....but on the whole deal. Or maybe a combination loss limit/risk of ruin plan to whereas if you lose say, 20-30% of the roll, you drop down a level until you rebuild to, or close to the original stake. I think I like this best. It gives the plan a chance to develope if the first few session are miserable.
