And depending on how long the line is, quite small losses in RG8 on 160M. 
37 ohms is quite close to 50 ohms, there will be at least a few ohms of 
resistance in the radials, so additional losses due to SWR are miniscule. 
Unless the feedline is really long (more than a few hundred feet) I'd go 
with RG8 that has solid copper center and a good braid shield. You do plan 
to stick with legal power, don't you?

Yes. The TenTec tuners will do very well with this antenna. Heck -- the 
output network in my Titan 425 loads my 86 ft vertical directly over at 
least half of 160M without a tuner, and the tuners do just fine with the 
rest of the band for SSB contests! And your antenna, being much thicker 
than my wire, will have signficantly greater SWR bandwidth.
