I've switched over to #12 THHN, and love it so far. I have a high full
wave 80M diamond quad loop made from it with fairly high tension on the
top half and have not noticed any lowering of resonant frequency so far.
Solid wire is nice cuz it's easy to clean if you need to re-solder anything.

Hi Dave,
Other than that failed experiment with FlexWeave when I got back on the
air in 2003, I've never used anything but THHN for wire antennas. For
low-stress applications (not very high, no tall trees involved), Our
dipoles for FD, that get strung between ad hoc skyhooks or to ropes
launched into low trees are all #14 THHN solid. I've been happy with
#14; for my high dipoles suspended between very tall redwoods and fed
with 150 ft or more of RG11, I've settled on #8 bare copper, stretched
so that it approximates "hard drawn" and about #9. I've done this
because even #10 stranded or solid stretches under tension, so I had to
lower the dipoles every few years to snip a few feed off the ends.
#14 solid should be just fine for your application. Just be prepared to
tweak length every few years. :)
