Whats up everybody. I hear the move from 2/4 to 3/6 is the hardest one so far in a poker player's career. I am here with only vague questions and hoping anyone who's been there can leave me some tips, advice, motivating stories, or naked girls to get me started.

First of all, should I even move up? I only have 54k hands of 400NL since the end of last month. The party 2/4 game is an ocean and I'm happy with the money I make now but still I've only ran at 2.5 ptbb/100. However my last 10k hands has been at 10.4 bb/100. Since I've quit my job and play all the time now, I realize how small of sample sizes these are.

What kind of bankroll should I have before jumping in? I've taken a few short shots at 600NL (about 1k hands total) but I've waited until I have $20k to take a serious shot at it.

How did you make the move?
Is it really that much harder or am I just being over dramatic?
Also, how do you store your roll when it gets to be $20-40k and above?

edit - this is all 6max
