Well I haven't played much $50nl (only 4k hands). About $1000 of my earnings is from MTT's/SNG's/FTR stuff, so if you look at only my cash game profit it basically follows my bankroll management rules ignoring any profit from other sources.

That and I love playing with a deep roll since it just gives that extra cushion to not worry about losing a few stacks. Makes it easier to just keep playing instead of worrying whether or not I will have to move down etc.
