So where does Petzl's new Spirit dogbones - made from Polyester - fit into all of this?

Polyester stretches less than nylon, but more than Dyneema. I would consider polyester to be a very low stretch material. Polyester slackline webbing generally stretches about 1/4th to 1/3rd as much as nylon slackline webbing. Of course we have to account for different weaves and material surface area, but you get the point.
