Inverness for speed, mostly as the roads are pretty good from all the way to Achnashellach at least.
A9/Laggan/Spean Bridge/Shiel Bridge/Strathcarron for better scenery!
For what its worth, I did Shieldaig to Fife via Glen Shiel/Fort Bill/Glencoe/Crianlarich/Stirling last Friday, just for the hell of it. Took approx 5 hours, and obviously not the quickest route. Actually as a detour from Ullapool! Silly thing to do, but enjoyed it all the way, what a drive that is!
The A87 Dornie-Glen Moriston is in a shocking state, by the way, even with some temporary patches added since I did it a month back when it was like rallying, dodging potholes and stones.
