I've used window line for many years and it is a maintenance hassle. The heat and UV here in AZ just eats the stuff up where it has to be replaced every 5 years or so, and I do twist the line. The last wind storm we had ripped the line right out of the DXE black plastic insulators which are not all that good either. So I am looking with keen interest at all these homebrew open-wire-line construction techniques.
YMMV.

I've heard that twisting that line solves the breakage issues. You need
many twists in the entire length of the line.



I want to replace it with parallel wires, which run through ceramic
feedthrough insulators


And, I've heard that running wire through ceramic insulators like that will
eventually abrade the wire. Holes in ceramic insulators are usually quite
rough.


I have no experience with either of the above. Here, we use plastic
electric fence and homebrew plastic insulators; and the wire drops into a
slot instead of having to string it through a hole. Works for me.

I think there's some photos at http://www.w0btu.com/Beverage_antennas.html .
