Maybe I should rephrase my question. Me and a buddy are having a little competition where we start with $40 and see what we can turn it into playing cash games only (full table). I don't think he has the ability to manage his money very well and will sit down at a cash table and either do well or go bust. I am going to incorporate Ferguson's strategy with the 5%/10% rule and see how it goes.

He only plays one table at a time and I multi-table, so to make it fair we will be using highest BB/100 as the winner over minimum 1000 hands. I know that isn't all that many hands, but at the rate he plays it could take awhile before he reaches that many hands

5% of my starting roll is $2, so which game on PokerStars should I be sitting down at?
.01/.02 game, starting the game with 100BB.
.02/.05 game, starting the game with 40BB.
.05/.10 game, starting the game with 20BB.
