In reply to UKC Articles:
I did it decades ago. My mate was more experienced with aid so he led, but at that time, the bolts on the last (aid) pitch across the roof to the lower off thread at the lip were worn ultra thin so he threaded slings through each to spread the load more than clipping krabs straight in.
The big question was would the bolts take my extra 2 stone when seconding. They did but we visited the cave not long after and it was all shiny new bolts across the roof. Somebody must have had a real trouser filler unzipping several bolts 😁
As in the article, don't miss the swing out of the cave from the lower off thread - it's ace.
Question: can anyone own up to having done the last free pitch (VS 4c in Paul Nunn IIRC) outside the cave from the thread to the top?
