In reply to GrahamD:
If you have the 2003 SWMC SE Wales and Gower guide, then all you're really gaining from getting the Gower Rock guide is photo topos and the recently developed sport climbs. If you don't want any of the sport routes, then the old guide and the topos on the SWMC guidebook will do the job. However Matt and Stu did an excellent job on the book and for the occasional visitor to the Gower it's well worth buying.
Al Rosier has done an excellent topo to Ogmore:

There is going to be a new Rockfax guide coming out to South Wales soon (as in drafts of it exist). So the jungle drums say.
As an aside, we're nearly out of guidebooks (a couple of 100 left) and no one in the club seems interested in doing a guidebook. If anyone out there wants to help producing a guide, then get in touch. We've got the money to print one. But really the wiki has replaced the guidebook and I can't see another SWMC produced guidebook ever coming out. There's a perception that guidebooks are something Rockfax/BMC do and only they can do it.
