Great roof problem using edges. Starts with right hand on obvious edge and left on a hold just to the left of the hold your right is on. Get your foot way out left on the horn. Big move up to a roof edge then you can do one of three things: 1) get a high dropknee on the start hold and reach for the next hold 2) just throw for the next hold or 3) figure something else out. From here the difficulty of the problem reduces greatly.
