Start on the largest corner on the crescendo ledge, with the small tree at the base of it, pro is good, get creative with using the entire flake, watch for poor rock quality near the fixed pin. Belay at anchors on the first pitch or fire through and link them(be ready for some hellacious rope drag, as well as communication problems) Second pitch is a lot easier. Anchors at both. Easier to traverse right out Buttpucker Traverse to get to the anchors on top of crescendo than to rappel down Moderato. Rap from Crescendo can be done in a single rap with a 60m rope, tho it is a rope stretcher.
Cams up to 3", maybe double #2 size if you dont like playing with passive pro. Cams, Nuts, Hexes, Tricams all very useful, esp. on the second pitch
