[TowerTalk] Durability of Mastrant rope

[N4ZR]

I have been using big box store "parachute cord" for antennas, but have 
found it quite fragile in real life - for example, the center support of 
my Carolina Windom came down within 2 weeks of my installing with with a 
tennis-ball launcher.  It was held up by a 70-foot pine tree, and my 
guess is that either the wind caused it to be over-stressed or chafing 
against branches caused it to fail.

Has anyone had experience - good bad, or otherwise - with the Mastrant 
rope sold by a number of ham radio suppliers?  Any other suggestions for 
support that may be more durable?  I'm willing to go to bigger rope if 
that would help - Mastrant quotes working strength of up to 900 pounds, 
but I don't know how resistant their rope is to chafing.
