What is the average strength (in pounds of pull) of a guy line tensioner? More specifically, what would be the min. effective strength?
I've got some small shock cord and it gives about 4 lbs of pull and I'm curious if that is enough to keep things tight, also don't want to have too much to where I'm continuously pulling too hard on the tarp.
I'd like to have the goldilocks meets ron popeil of line tensioners, not too strong, not too week, but just right, and I can set them and forget them.
So what has been your experience with tensioner strength?
