Thanks Steve. The Sierra Point Trail is one I was looking for. Also one called "The Ledges": an alternate route up Four Mile. I'm not sure if my group will attempt either of these. In general we aren't comfortable with too much exposure. But we did hike Half Dome, Whitney, and Angels Landing. And I like your shortcut to Cathedral Lakes but that will have to wait till another Yosemite trip when we are in that part of the park.
