Another question is when would you step down? The altitudes aren't hard, so there's a lot of benefit to staying a bit higher.

Haven't flown this approach, but it doesn't look like a slam dunk type approach to me. As you hit the LR, you are 17sh out, roughly 5550 AGL with a 10k MSL mountain staring you in the face.

If you start from Malad City, well, that would be a long drone if I expedited down to 10k- 15 miles + 12sh on the Arc + 17sh on final is 44 miles close to the Ground. Hate doing that when NY Approach makes me, don't see the benefit of doing so in Utah
