I don't think I'd want to be on a tower with temp guys that could easily
move 10-15 feet with a 100 foot guy line length. <:-))
Dacron and other synthetics give a little, but are far more stable than
Nylon which also deteriorates quickly in direct sunlight. I don't think
you'll find Nylon used by riggers very often.
