In reply to Barney_GT:
SMC guide NOrth East Outcrops covers the areas along the coast + clova, ballater etc.
For Dunkeld and others around the A9 you're looking at Highland outcrops.
whether you go for one or the other, or both, will depend on where you see yourself climbing most - personally I'd think more about the NE outcrops as it includes the angus quaries (bolted), clova (trad) and all the sea cliffs around Aberdeen (Trad mostly, some bolted).
Have a look at the SMC's website and it'll give you a good idea of area coverage.
Cheers,
