This route is left of the obvious arete (The Disclaimer). Many people find this route to be devious and difficult since all of the holds seem to be in the wrong direction. With that being said, you are on your feet the entire route. The crux is staying patient enough to figure out all of the moves.
You are on your feet most of the time. I got pumped on this, actually found some of the moves to be more difficult than that of the 11 b/c arete to the right.
