Topband: FCP versus loaded or "T" radialsradials

Elevated Radials ... In Houston, TX on a 60'X90' lot I had one quarter-wavelength elevated radial bent in the shape of an L to fit on the lot, it was routed around the perimeter of the lot.
At an apartment in FL, I managed to hide an elevated radial in the bushes with a 50' base loaded vertical wire hidden in a tree (a Stew Perry antenna).
In a cabin at a campground in Swannee, TN I had four 81' elevated radials (straight out of ON4UN's Low-Band book) up 20' and that setup netted me a top 10 finish, low power in a 160 CQWW CW test.
Now at my YL's QTH in Oak Ridge, TN (on a 1/5 acre lot) (fortunately she is also a ham) I have a single 1/8 wavelength linear loaded radial that that is also trapped (matches the vertical up a tall oak tree) to allow for 80 meter operation without relays. This antenna, while not a barn-burner, I was pleasantly surprised at its performance ... WAC with a hundred watts and have even run Europe on that unmentionable mode at 50 watts. All antennas were fed through a choke balun at the feed point and only the antenna with the 4 - 81' radials required impedance matching (used a hair pin).
I have sketches of most everything and I am sneaking up on 200 countries on 160. I hope this gives you a few ideas.

At the risk of setting off a food-fight, I'm
interested in opinions on
shortened radials (T or loaded) versus
the K2AC/W0UCE folded
counterpoise design. W8JI has an
interesting unfinished page
attacking the FCP.
Tom's a combative fella, but he's also
very smart. I am putting up an
inverted L, trying to avoid having to
lay down 6000 or even 750 feet of
on-the ground radials, and don't really
have room for resonant elevated
radials on 160.
