NC: Anyone else here do good at SNGs but bad at ring games?

A few times over the past few weeks I've ventured to nl ring games at party and I never come out ahead. If anything I lose money. This is odd considering my success at SNGs. I know how to read boards, put people on ranges, gap concept, yadda yadda. But the fishies get me everytime.

I wonder if there are SNG traits in some people and ring traits in others. Or maybe I just suck.
