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.
