In reply to street_alex:
You're absolutely correct in that a good selected guide for the area is now sadly lacking...
For Sport, the only worthwhile option is the excellent (but relatively expensive and slim) dedicated Wye Valley Sport guide. The CC guides including the supplement are completely out dated. However given how popular Wyndcliff Quarry is these days you're almost guaranteed someone else at the crag will have a copy if you're struggling to get by with just using UKC.
For Wintours Leap and Shorncliffe trad, the CC Lower Wye Valley guide (+Supplement) is the best option but it is hard to be too enthusiastic about it. The same applies to the CC South West Climbs Vol 1 but it does cover most of the routes that get lots of traffic.
For Avon, it is worth being aware that Rockfax West Country Climbs is as good, if not slightly better then the CC South West Climbs Vol 1. Both cover a very similar selection of c.60 routes. Obviously it is without any of the Wye Valley routes but you get the bonus of all the best Devon and Cornwall stuff rather than Dorset. (If you buy the CC Lower Wye Valley guide then that makes the Rockfax definitely worth consideration.)
For Symonds Yat, picking up the previous edition small CC hardback guide for around a fiver online and annotating it with grade changes from UKC is probably good enough for 2-3 visits. If you do decide you want return regularly then at least you'll know that it's worthwhile buying the latest version.
Not sure if that helps matters or confuses things more...
PS don't currently have anything particularly helpful for sale. Best I can do are a copies of the 2nd and 3rd editions of the Wye Valley and Cotswolds guides from 1962 and 1965 which might not be that useful any more
