Being tall is such an advantage on this climb! I would say v3- if you are over 6 foot. I am curious to what shorter people will do for beta.
Start on protruding flake below thin seam. Make your way up and right to the diagonal rail using the seam and other tiny crimps. Don't use arete. Although not really an eliminate because you shouldn't be able to reach the arete without going off the obvious line up.
