Hello, I'm a ground camper and i'm not making the leap to hanging just yet, but for rigging tarps- I'm intrigued by the low-stretch cordage talked about here. The paracord Ive been using is okay but stretchy.
I want to know if I can use lash-it 1.75mm and amsteel blue 7/64 for these knots:

truckers hitch for ridgeline
bowline
taut line hitch
alpine loop
sheet bend
double fishermans
