In reply to Hannes:
Northeast Outcrops covers everything north of Dundee, including Glen Clova cragging, the Arbroath seacliffs and the Angus quarries. The Cairngorms guide includes the Clova winter routes.
You'll be within an hour's drive of Dunkeld (out of date/print Highland Outcrops guide, plus selective coverage in the SMC Scottish Rock Climbs and Gary Latter's Scottish Rock guides), plus the Hawcraig and Limekilns (Lowland Outcrops guide) in Fife. There's also a new Scottish Sports Climbs guide due out this spring which will include all the latest sport climbing developments in the Angus area.
AVertical World is a good wee wall - you shouldn't have any problems meeting new folks there. You'll also be within an hour's drive of Ratho, and not much more than that to the new Climbing Academy in Glasgow.
