re Swildon's Hole Approach passage. I look forward to seeing Andrew Atkinson's comments re fitting P hangers. I have always found the natural thread belay at roof level adequate for lifeling from the streamway side BUT agree there is no adequate belay point in Approach Passage itself. I'd much prefer to see P hangers installed at Vicarage Pot and Northwest Stream Passage Pot. Perhaps the removeable footholds on the climb up the far side of Vicarage Pot could be fixed with resin at the same time.
