Looks good.
A long and twisty roads is what you are looking for and closer to home, I planned an over the week end ride to Wystheville VA. Then take 21 towards Damascus VA on route 58, then down towards Butlet TN on 91. If you've been to the Dragon, route 58 is a large version of 58 plus miles of it. Never been on 21 from Wystheville, but from what I am hearing it is similar to route 58. Going through these roads, you better know your friction zone and the used of the back brake. Anyway this a over the week end to explore these roads towards Boone NC via TN.
