Katz,

I agree with your judgement. One of my two fan dipoles is currently tangled in a big madrone tree -- but it happened because one of the ropes broke after about 8 years due to wear at the pulley.

Dr Rick-

If I had two clear supports, I'd do as you suggest. As things are, an extra
wire combined with March winds will result in a big wire rat's nest. My
antennas are threaded through the crowns of some tall oak trees.

YUK!  Why would you do something silly like that, Bob?

Why not just a double-dipole with the 40m radiator hung about 2 ft. below
the 80m radiator?
And in the meantime, the ONLY way I would address that task is with a simple
OCF dipole but you need a very special balun/choke design, then it will be
free (enough) of common mode current.

Trap = Crap.

I want to try an 80/40 trap dipole at the ATL QTH.
For this, I need some traps!
I am not keen on coax traps.

Preference is for some store bought, KW rated, like those used on Hygain
DP-2BDQ or some nice homebrew (vacuum caps and big coils). Do I need to say
cheap? :-) $60?
