The dukes pass is fab, but right now my favourite wee stretch is a neat section of road between Braco and Comrie, via Langside and Culloch,

This is short but very sweet. An excellent surface, with tight open bends and a distinct lack of traffic on it. Also when heading to Comrie you arrive on another great road, the A85.
I for one can't wait to see what our collective thoughts are on a map.
