This is sort of an off MTT topic, but it does have a big play a big part of the MTT grind, and since there is a lot of volume here I wanted to ask everyone a question.  I don't think it gets asked or perhaps I haven't come across an article relating to withdrawals.  So I have been grinding the micros and has a decent amount of success. 

**Stats filtered to the day I joined TPE**

                      Net Win                           ROI           ITM

  $2 MTT's

  $3 MTT's

   $4 MTT's

So I decided to move up in stakes and play more from $8 to the Big $27 and throw some $33's in there.  I'm sort of getting bored of grinding these stakes, as you can imagine… I played these for no other reason than to see if I can beat these stakes.  I'm getting deep in pretty large field tournies often enough I feel like I should be putting bigger buy ins in my game.  

My real question is when the hell should I withdrawal?  What sort of guidelines do people have in terms of managing an MTT bankroll?  (I don't have a bankroll persay, however would like to start working on one for Vegas next year but I do have a job therefore have essentially an unlimited bankroll… If I bust I just throw more cash on. )

Any answers would be appreciated!  Thanks guys!
