Quaranteenie

Start with left hand at the bottom of the left flake and right hand compressed on the slopey pinch next to the arete. Move up using the left flake and a right hand incut sidepull until you get to a diagonal ledge and a right crimp in the face at the top. Both aretes are OFF. A bit subjective where the right arete so refer to the photo for clarification.
