The apex is at about 70ft so I can reach the ends without much difficulty.

It is close to 3/4 wavelengths on each side which might be ok but the

My high 80M dipole is fed with 160 ft or so of a good RG11, but even
with that great coax, there's far too much loss in the coax for the
antenna to play well.
It might just be easier to toss up an 1/2 wave V and not worry about
the 80m.
Since I have the trees, I had the climbers rig 30M dipoles when they
were in trees for another reason.
Suggestions or comments welcome!
How low are the ends? If I recall correctly from when I modeled the 80
dipole on 30, it was a bit short, so switching in some inductive
loading near the low ends of the V might do the trick.
