My post shown below was in response K8RI's post regarding nylon rope. . 
K8RI stated he had severe stretching in 24 hours when using nylon rope to 
support a vertical antenna.  I said nothing in my post about using nylon 
rope for temporary tower guys.  Actually for my pier pin installation, I 
immediately installed the permanent guy wires after lifting the tower into 
position with a crane.  In the tower guy example K8RI described below,  the 
nylon rope would only stretch 10-15 feet if the temporary guy had zero 
tension and then was subject to a 30% load (about 1200 pounds for 1/2" 
rope).   This is a huge load change!  The original post by K7LXC 
suggested a way to pre-tension the temporary guy ropes to minimize this 

Nylon is resistant to sunlight damage.

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.
