I just looked over a few maps I have made over the past year, thought I would share some of these roads with you.
Now before I get started on these, I noticed that you had planned to do the BRP mostly on your second day. While it is a great road and is very nice on the NC side, I normally use it as a connector from one road to the next. I have been on it many times and at this point I have probably rode almost all of it. So these roads I am going to to mention are off the BRP and it can be used to link them up. I am going to try to list off roads from North to South.
Hwy 421 (The Snake)
-This runs from the Bristol Area down towards Boone. There is a nice country store at the bottom of the snake in Shady Valley.
Hwy 58 towards Sparta
-Goes through the worlds Shortest Tunnel. Serisouly they made the road go through a rock. Rather ammusing.
Hwy 221S
-Leaving Blowing Rock heading south. This road runs ll to the BRP.
Linville Falls
-This is just off the BRP, there is a nice park and waterfall there. Great photo op.
Hwy 181
-Runs from Jonas Ridge to Morganton. Nice twisty, fast road, extreamley wide.
Hwy 80
-North of Marion, NC. "Road so tight it will break a snakes back"
Old Fort Rd.
-Runs from Old fort to Hwy 9 (Marion)
Hwy 9
-Nice and Twisty, a bit populated. (Marion)
Lake Lour
-Very nice area. Dirty Dancing was filmed there.
Hwy 276
-South of Asheville. Tight and twisty. Great ride.
Hwy 215
-Leads to SC and Hwy 178
Even further south, in to SC.
Hwy 178
-Great road, nice country store at the end.
-Hwy 215
Take it north coming back from 178.
I just ran over a few nice roads off the parkway going North to South.
There is a great website that people can post and comment on roads for motorcycles.

I usually look for roads on there and then get on Microsoft Streets and trips and start playing around with routes.
This week is not a great week. But feel free to contact me at any time. I can get you some software to help with this and I can send you a few maps.
