If it were me I would never end up below North Georgia. So many roads to ride in the tri-state area.
This is the Richard Russell "raceway" Another Cherohala Skyway type road with little or no access for people trying to kill you. Visibility is outstanding for fast runs on this one and you can visit Helen Georgia at the end.

I'll get with some of my riding group and see if we can compile some nice routes for you to think about.
