I rode the north side of Loch Ness and really didn't find it that bad. Traffic was considerate, fast and straight road, lovely views. Hear mixed things about the roads on the south side, if you're doing a big day I wouldn't hesitate to ride on the north. The bits after Inverness up and over to Bonar Bridge were an absolute highlight of the whole trip so wouldn't want to be doing them late/rushed...
