In reply to clipskipper:
I'm not sure about downloads, but I do know the Avon and Cheddar guide has descriptions of most of the routes, but no topo. The Rockfax southwest climbs has a topo for selected climbs (Highway One, the HVS routes on the main slab and Pharos too iirc).
However, it's pretty easy to work out most of the routes from their descriptions on UKC..
