Thanks for the pics! Nice stuff.
Looks burly, but not as steep as it looks, I would think.
Following the rib would keep you safe until the last pitches, but it may not be the best (easiest) way, under ideal conditions. Looks really challenging, scary knife-edge shit, exposed with shitty pro, aid through the steep sections.
Hard snow and ice up avi paths, through cliff bands would make for faster climbing under ideal conditions. me thinketh.
