This is the thin system to the left of Tangent, and right of Born Under a Bad Sign that goes out a medium sized roof down low. The roof is awkward until you commit to the wierd layback and get your hips into the groove. The route stays after ya, especially on lead with thin holds/jams and technical stemming.

Surprisingly the gear is pretty good on this thing and I remember the roof taking an orange metolious (I think) underneath and good nuts just above. An exciting lead however.
