Last year I used my 80m dipole-110-foot vertical feedline as a top-loaded
vertical on 160 - it worked well as a transmitting antenna but was a poor
receiver due to noise so looking for another option.

Have you compared receiving on 160 meters using
the antenna in 80 meter dipole configuration vs
in 160 meter vertical configuration?  I suspect
it would make a nice RX antenna.  If possible,
use common node chokes on the feedline.  If
this is successful, install a TR relay system to
switch configurations so you listen on the
dipole and transmit on the vertical.
