Also by the CC of course! Does have a few photo topos of Shorn cliff (but even these are somewhat compromised by the nature of the crag, as mentioned by Ollie B). SW Climbs is a selective guide and if you depend on it alone it limits your options, used in conjunction with the Lower Wye Valley guide it may help you locate things on a first visit to Shorn Cliff in particular.
The 2012 Wye Valley Supplement by the CC includes some new and newly bolted lines, worth having too - just a fiver, or comes bundled with the main guide from the CC if you buy from their online store

Lower Wye guide is OK, but have a look at the new Pembroke guides before casting judgement on the CC's ability to produce a great guidebook.
