Interested to know whether anyone has experience using High Modulus 
Polyethylene (also known as Spectra) rope for guying towers?  Apparently the 
material is stronger than Kevlar, is UV stable, etc.

>From Phillystran website the description of the material is:

Phillystran high modulus polyethylene fiber ropes (PSPE) have been engineered 
for applications where lightweight, high strength and good abrasion resistance 
is important. Phillystran PSPE ropes are general purpose working ropes 
manufactured in a 7x19 construction with an overall braided polyester jacket. 
Typical applications where PSPE ropes should be considered are winch lines, 
mooring lines and towing lines.

The quarter inch material is listed on Phillystran's website as 7700 pound 
breaking strength - stronger than 1/4" EHS? - and the 3/8" is listed as 15,000 
pounds.  Lots of companies make it and from what I can tell the price is very 
attractive.  One company said for an extra six cents per foot it would have a 
black polyurethane coating for the purpose of shedding water.
