RIck,
I guess I would come under #3. I have a 6BTV vertical inside a PVC flagpole. It covers 80, 40, 30, 20, 15 and 10 just fine with my KAT500 tuner. I cannot work 80 SSB because the 80 meter "stinger" and coil just don't have enough head room.
I bought the tilt base and radial grid plate from DX Engineering. I have about 66 radials ranging from 55 to 10 feet in length spread in a 3/4 pie pattern. It performs as well as could be expected for a vertical, meaning beams will usually hear stuff I don't, but WSJT-X has helped greatly to mitigate the problem.
Hope this helps.
