Stand start in the middle of the face with a left hand on the large slopey sidepull and right hand on the juggy ledge out right. Pull on and go straight up to top out. A right heel may be useful for the first move.
No idea when I first climbed this. Probably when I was working Stir Crazy. Fun climb, and a good way to work the other lines on the wall since many finish the same as this problem. Not quite as full value as Stir Crazy though.
