In reply to BnB:
Anything that gets a lot of traffic should be ok
Paradoxically, in the wet, polished (clean) rock has better friction than the surrounding, less travelled, imperceivably lichenous stuff
(it's only in the wet you find out how often you pad up/ lean on the lichenous stuff)
Raven crag - Holly tree traverse is ok
Scout - Route One - more adventurous - less gear
White Ghyll - slip knot - IMO start p2 is crux in wet - fettle it with sling above you on overhanging lip
some descents are very serious in wet
