Dance from the face or the arete up till about 25 feet, swing over left and work up to a slab underneath the roof. Pull the roof at the v notch and finish out on a ledgey slab.
Be careful when toproping or lowering. Rope has the tendency to snag in the V notch. The roof can also be quite aggressive on ropes if you're swinging against it while lowering.
Start either on the face or the shared start of the climb to that runs up the arete and finishes out left.
