I was just having this very discussion with some one else this week.
We modeled a 100 ' tall T on 160 M with sixty-four 100' long radials
using NEC-4. with that many radials there was essentially no discernible
difference between #22 wire radials and #14 radials on average earth
ground. If you want I'll run the analysis using NEC4 again against your
smaller radial field later today. Give me the size of the vertical
radiator(L, T or straight Vertical)

For the moment at least, I'm using on-the-ground radials for my 160M
inverted L. Discussion on the reflector triggered a thought - is the
size of wire used for on-the-ground radials - or elevated radials for
that matter - significant? I ask this because I have a huge spool of
military-surplus, silver-plated (!) 18-gauge insulated copper wire.
Currently using 16, +/- 1/8 wave on-the-ground radials made with the
stuff. Feedpoint resistance seems to be by the book, at least as
compared to feeding the antenna against a single ground rod.
