Mambo- 6 tables..impressive. Best I can successfully manage is 4. And with this many tables, I dont refute your idea to stay lower.

On that note, I have had the same luck at $400NL as you are at $200NL. Not sure if its my inability to keep the same mindframe, or if I am looking at the bets and raises differently, but it is something I mean to fix.

Dunbar- I wouldnt call my playing "for a living". I am a college student with full-ride scholarship, so my room and board is paid for by the school. However, my only form of income for extracurriculars is poker.
