Well, I've worked a lot of good stuff all over the world on 160 with an
inverted L with two elevated radials - because that's what I had room for.
If you get up to 4 symmetrical elevated radials there's not much to be
gained by adding more. There's been a lot of work done in the broadcast
industry using elevated radials to replace deteriorated buried radial fields
that shows that pretty clearly. It was published in some IEEE transactions
some years ago.

The only real way to tell is have one of each, and do many instant A-B
comparisons over a period of time.
I just have two 10'+ high elevated radials on my bottom-fed L. It seems to
work "well", but I should add more radials this summer. And that's what I'll
probably do before I ever build one of those.
