I agree! 

Another thing people neglect is even a poor dielectric has negligible
effect is the electric field is mostly outside the dielectric.

For example, I use only 50 or so Lexan spreaders in my line and they occupy
a very very small area between the conductor. I care less how poor they are
at 30 MHz, as long as they don't melt from heat.

Now if I had the dielectric surrounding the wire for dozens or hundreds of
feet, I'd be a lot more concerned.
