Chip Reese comment as applied to Bankroll

[JasonDB]

He was quoted last night as saying he does not play in the smaller ring games because it does not hurt when he loses in those. He was not talking about hurting bankroll, he was talking psyche.

I have noticed that when I am playing within my bankroll 30-50x my buy-in for SnGs, I often take something of a complacent attitude into the game. However, if I play a little beyond my bankroll, I will typically play my top game. My thought is, why not play a few games a little above my bankroll, if I lose then back it down. Anyone take a similar approach? Pros and cons (aside from the obvious con that you run through your bankroll quickly if you are not ready for the next level or are running bad)?
