Plz do! Im fairly interested to know. Ive been wondeing since you posted. It also crosses my mind that it tends to be a stiffer hand, no? Not near as supple? I wonder how much that would affect the grab of the hitch...
Also if im remembering correctly.. Most polyester melting points are around 400°,
While the aramid in say something like sterling RIT is around 900°
Thats a pretty drastic example of a difference, but still..
