Moving up (and down) in limits: Bankroll ?

[gomberg]

Although I agree that working to 40 bankrolls can't really be too bad an idea - I've never had a downswing larger than 6-7 buy-ins in the last 2 years, and that downswing was at the higher limits. At the lower limits, I think my biggest downswing was probably 3 buy-ins. I may have been extremely lucky, but if playing full tables, I think 15 is plenty. I just moved that number up a little bit every time I move up a level. So for 5-10, I need to keep my bankroll around 20 buy-ins. I'll start taking shots at 10-20 when I'm at 20 buy-ins and try to play it a lot when I'm at 25. - and so on. It's worked for me so far.
