I own three Jingo-Wobbly guides, and aside from having a rather silly name, they're all of a very high standard - certainly the best guidebooks for climbing in my opinion. The pictures are excellent and make finding routes on a cliff face nice and simple, the descriptions are concise, accurate and helpful.
This is the must-have guide. Just perfect and clearly illustrated with great photos and every route described. Also useful, is access information on how to get o the top of the routes, plus where to park.
