Behold!
The best houseplant/landscaping plant sling material (in my opinion).
I made a sling in roughly 2 hours from it. The sling weighs only 10.4 g and is very strong. The cords are so light I don't think it would have much of an abrasion problem (to be determined).
You can scrape off the non-fibrous material, similar agave (sisal) in this video. But I did not.

I went to my local nursery and purchased one. Worth it for sure. It's a perennial, so it should live for a while. This is a small plant. Some grow to 2 meters tall.
Update: Here is a video of the fiber extraction process.
