In reply to Jamie Bankhead:
More accurately, that 'kind of thing' happened once! I won't disagree with the sentiment that the easy routes at Castlebergh aren't very good but that is not the same as being dangerous and over the course of the last 18 months surprisingly little has fallen off despite their loose appearance. Of course it is recommended to wear a helmet because, like all easy yorkshire limestone, it is possible to dislodge small rocks.
Really though you need to be climbing 6c - 7a+ for the better routes there - other venues are definitely better for 6b and below.
Regarding quickdraws, the longest route at Castlebergh requires 14 or 15 but everything else can be done with 10 or less.
I would actually recommend Moughton Nab for low grade sport routes. I've done quite a bit up there this summer and whilst short, the routes are often surprisingly good fun.
