I agree, go with a super light rack. There is really only two short sections that most will place pro. It's implied in your post, but you want a few slings. Slinging horns is quick, easy and usually bomber.

I'll need to look at my chocks, but I believe that it was a #5 Wild Country nut.
Just past the Snowbird Lodge, take the upper entrance to the 2nd skiiers parking lot. There is a shack just past the entrance, and the turnout is right across the road from the rocky headwall of the South Ridge. Parking restrictions were from 12am-8am, but there were people parking there before 8 when we were there.
A shuttle would be the most convenient, with one car parked at the Alta Ski Lodge if descending via Cardiff Pass.
This is described for a winter route - there may be better variations for the summer route.
After crossing the highway, head diagonally right to the far end of the cliffs to meet up with a small chute. Head up this chute as it cuts across the cliffs. (Moderate Snow or class 2)
