When looking at the trail-facing roof, this problem climbs the right blunt arete.
Stand start under the arete with a left hand under the roof on a left facing flat sidepull and a right hand on a small slopey lip at the base of the arete corner. Heel hook up on a rail with your right heel.
Bump up onto the massive bulbous sloper feature and work into the small crimps. Negotiate to the top.
(Your doing something wrong if you need to go left or scrub anymore than whats clean... climb straight up through the arete)
