I've had my copperweld 80M dipole up between two Douglas fir trees for
around 30 years. I did find that you need to be very careful not to kink it
as you're working with it, or the steel inside cracks, leading to breaks.
But once I learned that, the copperweld is truly hell-for-stout!

W6GJB had the same experience.
The #8 we have stretched to #9 is pretty strong, stronger than THHN, which
stretches when it's under tension for a while. The 80M dipoles I built with
#10 THHN had to be lowered and circumcised every few years to keep them
within tuning range of my 87As. I've not had that problem with the
stretched #8, which is very close to being hard drawn.
