They can survive a 500m pull (in 100m stages, or the friction is too high) in mud and rain, through active water line.

Honestly, fibre, even unarmoured with just a standard Kevlar & HDPE sleeve is hardy stuff. When I first started mucking around with it a few years ago I was like “don’t breathe on it too hard”, now I’m like “tie the fibre in a knot on the bullbar and pull it with the truck”.
