I hate rappeling, it is dangerous.

Try it out of a chairlift that's 70' above ground. No rock to push off from
or to land against--just air.

We used to do this with 5mm Perlon when I was a pro ski patrolman at
Breckenridge in the 70s. The Perlon was good for one trip only, and it was
approximately 30% longer when we hit ground. This was SOP for
self-evacuating a chairlift in the event of a breakdown.
