Is Dyneema or nylon better?
Dyneema is impressive because it has a much higher strength to weight ratio than Nylon. Mammut reports a tensile strength roughly 15 times greater than steel and 40% greater than aramid (Kevlar) by weight [pdf]. This allows Dyneema to be about half the weight and width of nylon.
How do you finish off lashing?
