I don't have a Hex beam, but for my wire antennas strung in the trees I use
this stuff:

It has survived nicely holding up a wire antenna for ten years so far in
high winds, sunshine, rain, snow, and freezing weather. It's hard to imagine
that a Hex beam would put more strain on it.
However, I am in Oregon. The rope is advertised as UV resistant but we don't
get nearly as much UV as some other areas. (Sunblock salesmen go broke
around here.)

Why do you think it will "significantly outperform the hex beams?"
The point about uv is well taken re fiberglass, but I don't know what the
cords on all the hexbeam versions are made of. There are uv resistant
materials available.
I wouldn't say an 11 element yagi with capacity hats on the elements has an
especially low visual profile!
