I agree.. nice posts spoon.

I'll even take it a step further... for a serious player... bankroll shouldn't even be an issue for games in which you are regularly playing. What I mean by that is say you have $4k and want to know if that's enough for 1/2. Maybe it is, maybe it isn't (I'd argue that it most certainly isn't). More importantly though, if you're good enough to be playing 1/2, then you should be able to grind out a LOT more than that at lower limits, and by the time you start playing it, the size of your bankroll should be more than adequate for it.

I think this applies much more to seasoned players who have logged tons of hands than someone trying to aggressively climb the 'tree' so to speak. In the latter case, the experience of playing more hands will help develop you as a player which is more important than short term profit anyway.
