#10 Stranded Insulator wire simply doesn’t break… maybe the rope will though…
One time, a 90 ft pine tree blew over in a storm with my 160m dipole attached
to the top…
The antenna wire kept the tree from falling on the power lines on the road, and
instead fell laterally and broke into several pieces.
The antenna still worked even with the tree down (SWR changed some) !
I unraveled the wire from this mess and put it back up again… It’s still up
there, several ropes have broken though ! that was a dozen years ago!

Here in Florida where high winds are fairly common, I use the Davis FlexWeave
insulated wire and, in the case of loops, "float" the wire, allowing it to
slide through insulators at the corners. I terminate it at the ends with
dipoles and use 5/16" UV stabilized Dacron line through pulleys to weights
keeping it taught. When the trees I use as supports sway, the weights go up and
down, keeping a standard load on the wire and moving the friction point a bit
to avoid single point wear.
It has been up over two years now, gale force winds on a number of occasions
and no failures! (Knock wood.)
Tough wire. Same as or similar to Wireman Silky.
