Finally pulled this climb after committing to some very smeary footwork. I climbed a thin route up to a solid undercling and straight up a second very cruxy slab at the finish. You have to really trust the rubber on your shoes for the polished holds.
climb the left most side of slab (to the left of the crack), stay within two feet of the right facing wall to the left. helps with commitment to good feet and trusting them. didn't use feet/hands/body/other on the right facing wall to the left, although it was quite tempting!
Sustained at 5.10 for the first 15-20 feet. Made all the more difficult by the extremely polished foothold at the crux move. There is another crux at the top if you don't use the crimp to the left. It's about 5.10 if you're 5'8 or taller, and 5.11 if you're shorter.
