In reply to Dark Mavis:
Thanks for all the responses, sorry but ive been out of the house, hobbling up to have tea and cake with some friends!
No not a troll, heres what happened and its all my fault.
Abbed down to put a lower-off in a new route (route finishes a way below scrappy top), after putting the pegs in i realised i had left something at the top (including my slings). Attached my shunt above me with an old sling/tat that was with my pegs etc, took myself off my belay device and prussik so i could shunt up. Weighted the shunt then realised that the sling/tat on the shunt was one that i had found a while back and was just about to back it up when it failed.
I managed to retrieve everything apart from the shunt and sling so i havent had a close look at them.
Although very shocked, with mangled hands, i don't feel put off at all, in fact i will be back there asap to finish the job off!
