from half way up chocsuker, take a steep handcrack to a chain anchor (Fixe SS, 2x12mm x75mm Triplex). 2nd pitch is the meat, bust up the steep slab via some balancy moves on water runnels, to finish steeply via technical nibnobs
bolted (10?x 3.5"x3/8 Fixe PS), To (2x1/2"x3.5") ps fixe rings. no extra gear needed for second pitch. From the top, a single 70m easily gets back to the belay. From here do a short abseil to the 1st chain on sixtoe as you wont be able to get back to the ground with one rope.
