I like the Pig Trail, but it can be a very busy road at times. They also seem to always be doing some sort of road construction. My favorite road in Arkansas is Push Mountain Road. Not a lot of scenery but a lot of great curves, and almost never busy!! I just completed a video from my last trip!! It is a road that after you complete it, you want to turn around and run it again. I enjoyed your video!!
The Pig Trail is a nice road, but over rated in my opinion. 123, 341, 103, 74... all really good roads to ride. Hwy 16 would probably be on that list, if they would resurface the road. The same with old hwy 71.
