I recall that either Rudy or someone else has shown that a "gullwing" arrangement where the elevated radial has a sloping section that goes down to a ground-level feedpoint works well, so you wouldn't have add to the mast in order to use it. AFAIK the main drawback with a single elevated radial is that it will be noticeably directive, maybe not a drawback in every situation. When I used two elevated radials, one formed a half circle around the house, under the eaves, and one followed one side of the house and from there went close to the property line to a pole on the back fence. That way neither wire got in the way at all, but every lot is different. Anyway, I am not advising against a good buried radial system, but I do suggest that when you have put it in to an extent you are comfortable with, just string up an elevated radial in a temporary manner to compare it to. The performance of an elevated radial is less subject to all kinds of design considerations, so it is a rather good standard against which to compare. (I am assuming you trim the length to have a resonant system. If you use more than one, and want full benefits thereof, you need some way to compare currents in them, as any difference in geometry tends to produce very unequal currents in equal wire lengths.)
