Comments: Fun times! This really is choose your own adventure climbing. Be ready for some runouts, but generally excellent pro when you get it. Also agreed that most of the climbing is 5.4ish, with a touch of 5.7 here and there.
FYI: We did this in 3 pitches with a 70m rope, running the rope out pretty much each time. That got us to the big ledge at the top, and we 3rd classed the last 50 feet to the ridge.
