In reply to MorrisRodham:
Sub-Cneifon Arrete/Rib.I've done it in big boots when it was part covered in ice.
Lockwood's chimney is more of a squirm and should be done in old clothes.Look on previous threads for how to get there as identifying the start can take as long as the climb if you are not careful.Worth doing just for the kudos!Lovely view when you come out of the top.It reminded me of that underground route on Skye which is bloody good fun.
What about the diff on Bochlwyd Buttress,Arete and Slab.
