If it is a solid 2000' then the coast is the obvious option.
Aberdeen will give you a transit - unlike many Class D units they actually live up to the rules and expedite traffic. Just sound sensible and you'll get the stonehaven followed by Inverurie or Peterhead land - but you need to say which!
At Aberdeen you have the choice of swinging inland and heading toward Nairn (the Inverurue lane!). The majority of the danger areas will be cold at the weekend unles there is a major exercise on, so they usually do not present an obstacle.
If the cloud base is solid and low then it can be a bit of a trek around the coast otherwise (Peterhead lane!).
IF the cloud is 2000 and well broken - then the route up Glenshee and the Lairig Ghru will quite possibly be passible. The massif tends to cause these clouds to break up, so in a SW or W there is often a few ways through south to north.
Given the pessimism of the forecasts these days I would try the direct route and divert east if necessary at Braemar. Of course if you cannot get to Braemar then it's the coast of nothing!
