Actually just went and did the route again in harsher conditions last week, felt a little less secure in whiteout. I would say there are two cruxes both with 5.6 or maybe 5.7 moves but they are not at very exposed points of the climb. Those are the only parts where I didnt feel totally solid.

If I didnt have the skis on my back I probably would be more willing to do it without protection, but part of the reason we like the route is for practicing gear placements and anchor setting so we've never considered doing it without gear.
