I am in the process of making guylines for my MLD Poncho/Tarp.
My question is: How long do the guylines need to be to allow a good variety of pitching heights without "excess" line?
I am planning on attaching the guylines to mini carabiners to facilitate quick and easy attachment & detachment. I am using the BMW AirCore Pro Shelter Guyline Kit (with the cam-locking tensioners).
