Immaculate rock and a slick slopey crux. Stem up tree for a metre to gain rock then take left line of bolts up very nice pocketed grey wall to blankness and big bolt. Sneak left to find hidden pocket, fiffle with some sketchy feet then back right to big sloper pocket. Long move then finish up orange bulge. If you lower-off the big bolt at the half-way point its a classic grade 16.
