I have a mish-mash of long, short, insulated, bare, solid, stranded, thick, thin, on ground and below ground radials for 80 and 160 that has accumulated over the years. It doesn't matter. What matters is how many and length (coverage) with rapidly diminishing returns after 60 or so. Plenty of research to back that number. Make them as long as you can and as symmetrical as you can for the land you have. If you have land to do a beautiful circle of perfectly sized radials, great. Otherwise do the best you can. Point being there is no reason for hand wringing over it. Tenths of a dB on the low bands just don't matter.

burying the Radial ends if installing less than 60 radials.

There is ZERO reason for radials making electrical contact with the earth. Their function is to provide return current for the antenna IN PLACE OF the earth, which is very lossy (that is, it wastes transmitter power), and to SHIELD the antenna's fields from the earth.
