Heh, that leftward traverse was an entertaining scene for us on Dragontail, as well.
me: "@#%$, I'm 6 feet to the right of the notch!"
partners: "Awesome! Nice!"
me: "Not awesome. Not awesome at all."
I agree that it's a 10a/b traverse, and certainly exciting. I also agree that the third couloir of the triple is lined by the most heinous arrangement of boulders in playdoh I've ever experienced.
Nice work on making it up and down safely!
