In reply to Sl@te Head:
Thanks for the E4 list Ian.
Though Sweetest Taboo and Slug Club likely violate the "first gear at ludicrous height" criterion. Also I likely wouldn't stand a chance on 6c routes like Menai Vice and Putting on Ayres (I found Watch Me Wallaby hard enough), and I'd likely be equally bad at routes described as a "total pumpfest" like Ride the Wild Surf.
The Gorbals, though, might go on the list. Maybe also Men at Leisure.
