I think some of it depends on how well you play a relative short stack. I play the 11's and on the weekends, genereally it seems that that there's one or two giant stacks by the time it gets 5 handed. I'm usually still hanging around 800-1000 chips at that point, compared to their 2000-3000 chip stacks. I seem to have more variance on the weekends, but my ROI is higher.
