It doesn’t weigh less than using hangers. Most of the belays have krabs on. It weighs a lot more than using bollard type hangers. You have to spend £700 on string you prob have little other use for - ie the cost of nearly 100 hangers and maillons. If I was rigging it now I would prob take some cord on the assumption there are hopefully some better placements than before. I count 16 belays on Gontards compared to about 6 before, has this pitch been designated for SRT practice or something?You could probably carry all of that in 1 tackle sack! I love that magic string!
