In reply to John Gresty:
There is a guide being put together but at the moment I don't know how far along it is, last I seen all the venues had been written up but maybe they needed some final adjustments or something, agreed with the other poster that you should reach out to Lee but I'm not sure if you'll get a reply, you might though.
As to Hollinhill, much of the land surrounding the main wall is private and there's quite a lot of loose rock around, the main wall is excellent though and there are also problems on the boulder just off the approach and another wall to the east. As I remember there's plenty of poison ivy dangling about and very little in the lower grades.
