One of my favorite problems. Start with your left hand on a slopey rail under a small roof and your right hand on a sidepull sloper. Put your feet on and throw that right heel up to your right hand. Dig that heel in and move/slap your way up and left on the lip around the arete to some pockets. You can finish by continuing to traverse left or up the slopey arete with a hard top out. I've never done the left finish, I always go up the arete which adds a second crux and puts it as an easy v6 to me.
