[TowerTalk] Black rope

[JC Smith]

It's good stuff for many applications but not good for permanent
installation in trees unless you can keep it from rubbing on branches.  The
Dacron jacket is fairly thin and will wear through.  Then the sunlight
destroys the Kevlar and down it comes.  At my old QTH in windy SD, antennas
in the trees (just launched up over the top with my wrist rocket, no
eyebolts or other) would last about two years with the .075 Dacron/Kevlar.
That was OK as the support line was easy to replace.  In SD bows and
slingshots aren't considered "firearms."  Hell, in SD guns are barely
considered "firearms."

This is great information.  This 075 rope solves my
two complains with the usual black rope.  Stretching
and wind area.
