Wow, I've got to try a PR, looks excellent. Prime-Rib is about my favorite cut of beef nowadays, and what I order when we eat out. I can never get a good medium rare piece though, it's usually more medium +.
As far as resting it for 1.7 hours, I'll tell my wife to get the other sides ready and on the warmer on the stove, and have them wait for the PR!
Great job Crewdawg!
