Tnx to Hector, xe2k, for catching the typo. NOT 7700 lbs!

Radioworks kevlar/dacron is rated at 770 lbs static load,
which is approximately equal to the 3/16 dacron line they
offer, and a bit less than half the rating of the 5/16 dacron
in their catalog.   

Nonetheless...it goes up ok, but it will require some means of
peak load release,since it doesn't stretch.  Haven't worked out
that system, yet.   Maybe a bungie bundle,  maybe a dockline 
"snubber".   Maybe nothing, and see what breaks.  

Last night's squalls brought down a 4" branch from one of the
trees...what breaks could be interesting!  To be continued.
