Tim, I'm not being a wiseass or anything, but maybe that's why it's called sixish. It's been a while, bu I do seem to recall saying just about the same thing you just said.
RR
RG beat me to it, but that "common" knowledge about the name was reinforced (maybe started?) by Swain in the old guide where he made the crack about the grade.
So, can anyone actually answer the question about going straight up over the bulge left of the roof, instead of traversing under and going through the notch ?
Sounds as if we came to the same conclusion about P3 then RR. And from what I've found scattered on the intardweb, it seems a bunch of other folks have also, some of whom (like RR) have opinions I trust.
I can't believe I've been climbing there 20 years and had never done that pitch. At least I don't remember it and I did not have it noted in my guidebooks.
