Topband: Low band antenna project questions

OK, still working on my permanent low band antenna and what I can fit 
for an effective antenna. The space I have is a recently cleared forest 
area. I had originally considered a full size loop but the best I could 
do is 50' high, although that would be a bit higher than my temporary 
dipole it is not much in the scheme of things. And I keep getting talked 
out of it.

I have walked the back many times with the tape measure and lines to see 
what I can fit, and what I can fit is a catenary line to support a T or 
L at 50' above ground. And after reading numerous articles the consensus 
was not to use radials much longer than the vertical height. I can 
easily fit 32 radials @ up to 75' each.

Now I want to be able to use this antenna for 80M as well as the non-DX 
portion of 160M. I can house a autotuner at the base (or make my own 
network but that would require control lines). My thinking is to make 
the 160M a 5/16 WL vs 1/4 to be more beneficial to 80M tuning without 
loosing anything on 160M.

With the above limitations is this an effective solution?
T or L ?
Am I missing anything?

Working on a RX antenna later.
