Have a good trip
I'd take the second of the routes posted today for better radar coverage but if its CAVOK then the first is certainly more scenic. Per an earlier post I wouldn't head into the mountains with anything less than stonking vis and the right cloudbase - the aforementioned 2000' is a definite "no no" on route 1 and perhaps even a bit marginal for most cross country routes north around Aberdeenshire, Moray & Highland. Bag every foot you can get! And the view's better!
Previous post offers good advice on wave. Read up, keep the VSI in the scan and you'll be fine.
Enjoy the views and have a great trip.
