tim.rose2 said:In terms of vertical caving - we're very used to abseiling 10 - 20m mendip pitches just tend to climb back out on ladders rather than srt as two of the group don't own srt kits. Probably not the most common or modern of practices but its what we do, works for us and is safe.
Why not buy or acquire SRT kits and become proper cavers? Ladders are sooo1970s...
