Whats the difference between:

Amsteel - Samson (sk-60 dyneema fiber)
Ultrex - Yale (sk-75 Dyneema fiber)
Vectrus 12 - Yale (Vectran fiber)
Samson Tech 12 - Samson (Technora fiber)

I've used Amsteel and it is slippery so the knots take a while to set. I've got some Amsteel trap lines with a spliced eye on each end that I'm planning to use on the Acat for trap lines.

Anyone else have comments on these lines? The commercial names make it confusing and hard to compare. They also dont list stretch as a percentage, but they say "low stretch or zero stretch." Is low stretch 5% or 2% or what? Is zero stretch really zero stretch, like wire?

Any other high tech single braid line that you recommend?
