We used several lanyards, found that many would break. We had Cetecea make up one that does not have plastic connection parts or coils. Ours uses 4000 lb test webbing sewn through (no plastic clips) with a ss clip or bolt snap and extremely stong parachute cord. We've sold these for many years without issue.
