well my tarp and guylines came in today and i cant wait to set them both up. I got the speer no tangle guyline so its just a long 100' piece. I have the 11X10 JRB tarp with several places to attach a line. So what is the best way to do this? I have seen guylines that have a bunch of loops in them and you just put a stake in the loop of your choice. is there a way to make the lines adjustable? what is the ideal length for the lines?
