A superb test piece at the top of the grade scale. From a stand at the bottom of a curving rail, smear the right foot and grab an odd gaston on the rail with your right, then place your left foot high on it. Pull down hard with that toe and bring the left hand to a sloping crimp where the rail ends. Swap the right hand down to a slopey undercling, raise the right foot, and throw roughly four feet to a tiny incut. Hold it, snag a jug to the left, campus across, and mantle.
