There's a very small difference in skill between the 5+1s and 10+1s. If you have the bankroll for 10+1s, play there instead.

Most of the posters here exclusively play NL SNGs (including me). Any reason you go with the limit SNGs?

Probably because the only people playing limit SnGs are people who were trying to play NL SnGs and a) suck at limit and b) are now on tilt due to signing up for a limit tournament.

Limit cash and Limit tournament are drastically different games too, by the way.

I play limit sng's sometimes. There is almost no difference in play between the 5+1 and the 20+2 at party. Just a bit more aggressive in general as you move up. Xaston is right, probably half ot hte people that sign up for a limit sng did so by accident. If you are beating the $5+1s, you should have little trouble with the 20+2's.
