I also looked at my old home-sewn slings (1994?) on my ascendeurs , particularly in the light of Richard Delaney's research on the Rope Test Lab where he found nylon slings more than 10 years old were all below half strength.
The loops at the ends were also very worn so I thought failure would occur there or in the stitching.
We were all surprised that the sling went in a relatively undamaged area away from ends, wear points, or stitching, at 5.7 kN, almost a quarter the strength of the original tape.
