I can sure tell you about the Talladega one, I live there.
It is not very long, maybe 30 miles end to end, some good twisties and road condition is good to excellent. The HIGH light is Mt Cheaha, highest point in Alabama. I live 12 miles from there.
You would be welcome to come by on your way, we could convoy up along with some others from Georgia and the Carolinas - plan right now is to meet up with them somewhere around Memphis.
