I've been told that modern copperweld doesn't have anywhere near the

That hasn't changed much - there's three kinds of Copperweld rated in
terms of their resistance as compared to copper, 21%, 30%, and 40%,
which determines how thick the copper is.
The old wire lasted. I think W6AM used it with his rhombics
and I never heard of Don having to replace them every few years. And
he was near the Pacific with the salt water problem.
I don't know that his antenna farm was close enough to the ocean to
have salt problems. It's about a mile from the shore (approx Portuguese
Bend), on top of the hill at 1100 ft - he wasn't in "beach front property")
(google "Palos Verdes Peninsula Crest and Highridge" to see where it
was. https://goo.gl/maps/nPYFBfoW1n8WPg1X9 ) Or google "Wallace Ranch
Palos Verdes"
