So, probably 15 years since I've been on this one. It's getting a bit slicker, d'oh?
Bit of possible beta: get your left hand in above the overlap, thumb up, and use the inner edge. Get your right hand above using a thumb cam, thumb down. Work the left foot as high as you can below the overlap. Hike the right foot onto the crescent dish out right. Work the weight up as high as possible. Deadpoint with the right hand for the edge on the right edge of the crack. Match left hand just left of the crack.
