2. Up the east coast and then keep west of the Aberdeen CTR routing via Bancory/Inch. This stays clear of the higher aspects of the Cairngorms and you can cut the corner depending upon the cloud. This takes you quite close to RAF Kinloss and Lossiemouth. Lots of Tornado traffic so LARs service is a good idea.
Just watch for Aboyne Gliding Club where you're over that way - if the conditions are nice it can be quite busy around there, but Aberdeen Radar are pretty good about letting you know if the gliders are out and will let you transit through the zone out of the way of the gliders, so it won't be a problem.
