I'll second that I believe limit has a much, much lower variance than NL. I know at least for me it does. At a bankroll of $150, playing $10 NL tourneys, I'd keep shifting between $50 - $200, playing very tight, very aggressive. I noticed many times really good hands were being beat by bad calls and would either put me out of the game or so low that I was barely hanging on. (I'd generally finish not worse than 5th). Playing limit though, I'm to $700 in four days ... I've had a few bad beats, but overall they don't hurt nearly as much as they do in NL.

I'm sure playing style also affects the variance, since I know sometimes I've bet too aggressively which ends up hurting me in the end.
