Requires a 50m and 25m. Not done this one before and despite trying to find someone to cave with I could not. It was an interesting trip in that I was not expecting it to be wet or tight, the second pitch head is akward but not as bad as say Large. Last pitch was very wet when I did it and I noted flood debris on a ledge 10m above the floor in Hunt pot. It was only 3 hours of a trip.
