Just to be a voice of discontent:
I use 7/64 Amsteel for my tarp ridgeline. Only because I carry a hank of it in my bag for "anything/everything", and it usually winds up being for the tarp. I could save a few grams going to something smaller, sure; but what if I need to pull a car out of the ditch on the drive home?
It could be that the purpose of my life is merely to serve as a warning to others.
Thank you. I like the way you limited the amount of stretch.
"Climb the mountains and get their good tidings.
Nature's peace will flow into you as sunshine flows into trees.
The winds will blow their own freshness into you, and the storms their energy,
while cares will drop away from you like the leaves of Autumn."
