On the contrary. It makes exactly the point that I would have made 
had I taken the time to respond, and in words I would have been 
pleased at having put together. The only significant characteristics 
of radials is that they are conductive and that they remain 
conductive and intact long enough to be worth the trouble to install 
them. The virtue or larger wire is that it is a bit more rugged than 
small stuff. The virtue of insulated wire is that it takes longer to 
degrade in corrosive soils. (Likewise, an important  virtue of one 
means of termination over another is how long that termination 
survives weather and soil chemistry. 

The ARRL Antenna Book has an excellent discussion of radials, how 
long they should be, the tradeoffs between length and quantity, etc. 
I believe that Rudy Severns is the author of that section. 

I also agree with the post (was it yours?) noting that what really 
counts is field strength. But as that post noted, ground 
conductivity has a lot to do with the importance of radials -- that 
is, the worse the ground, the more important radials are to good
