Hi, Took a fall leading a climb a few weeks back at Churchies. Was getting quite dark so had to bail out and leave 2 nuts on the climb that were a bit fiddly to get out in the dark. One of the nuts took the brunt of this fall, so if you are thinking of using the nuts rather than posting a message and returning them, then think twice about their safety…….it was a good distance fall (was just sorting out the next bit of gear near the top of the climb when I slipped). If you do have them to return, one of theem is still good to use.
