When are you planning on doing them? I might be in town. I've been wanting to do the ridgeline for a long time now.
I don't know much specifically about that part of the ridgeline, but when I was doing the Triple Traverse I met a couple finishing the route. They said that they only used their rope for rapelling (once I think?) near the beginning somewhere past Monte Cristo and that that area was the hardest part of the ridge with class 4 scrambling.
