In reply to dougp87: I saw you have already been to the Whangie. I think it would be alright, of course it's a bit loose but would probably be ok.
V. Diff always seems like an akward grade at the single pitch outcrops (at least around here?) They're usually a bit scrappy. Raising the grade usually gives cleaner rock.
Quadrocks is good, lots of Diff-Severe on rock that is similar to the Whangie and solid.
If you raise the grade a little, Craigmore is best in the VS-E1 range.
I think Dunglass is (generally) scrappy easy routes and death-on-a-stick hard routes. Haven't done so much there but have walked around it a fair bit.
And I'd recommend Auchinstarry, too. Again, better VS/HVS to the mid E-grades. But there are some Diff/V.Diff level that are good.
Off topic, anyone else have a mental block about the easy car park crag routes at Auchinstarry? Scream, Anarchist, etc.
