Mescal should be part of your loop. Something like Chuck Wagon, Mescal, Aerie, then whatever to round you out.

This is a slightly better loop but does not hit Chuck Wagon:

I would park in the spot in the second link, then ride the start of that, add Chuck Wagon to that loop, then follow it to the parking lot.
If you want to opt for 1 of the 3 Hs I would suggest Hiline. Hogs is a grade above that and Hangover is where people routinely hurt themselves because it's pretty exposed and high risk.

That is some solid scenery, but also more technical than the Mescal area. And while it's not a lot, there is definitely some gnar in the end of that Hiline loop.
