Sandrider

Sit-start in the same spot as "Catalyst" (you can start with right-hand on the sloper-rail already, though). Climb straight up through some crimps and pockets leading to a huge reach up and left to the lip/arete. Then head up and right, along the lip, until you can throw a heel up into the obvious shelf/scoop feature. Mantle onto the slab, and continue up to the top of the boulder.
