US 231 between Fayetteville and Shelbyville. Well banked 2 lane with LOTS of curves and light traffic.
SR129 between US231 and Lynchburg connecting to SR50 from Lychburg to Winchester Tennessee. And while you're near Lynchburg, stop and do the tour of the Jack Daniels Distillery and the Walking Horse Museum. The town is rider friendly and has a great rally the 3rd weekend in June.
