Disrythmia

Start with a right hand crimp about 6 feet up under the roof and left hand on the arete on a pinch sloper with a thumb catch (only thumb catch) also about 6-7 feet up. Slap and compress your way along the arete and rail under the roof to the apex of the boulder. Use toehooks, heel hooks, and some hard narrow compression.

A stand start from the arete and the largest part of the undercling exists, clocking in around V6-8.
