I remember it being pretty straight forward, they view from the col looks intimidating but there's a nice sidewalk on the north side. Select climbs mentions a 5th class step and we stayed climbers right on the way in and down-climbed the left side on the way out. There was a rap sling here and that was the only spot that I thought could be 5th class on the ridge. The views are great from the ridge, here's some pictures from a few years back.
