Found out some interesting things :
1. I thought Vectran was kevlar...it's not
2. Spectra and Dyneema are basically the same and both exhibit creep i.e they will stretch permanently under load.
3. Dynex is an "improved" Spectra that exhibits less creep than Spectra, but is much more expensive.
4. Vectran has strength similar to kevlar and exhibits very low creep.
12mm Vectran is what I have on Elyse for the main outhaul.
