And I wouldn't use anything but Polygon structural fiberglass guys.
Non-conductive, stronger than EHS, and more durable than Phillystran. JMHO
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I've used large quantities of both (and 502 alternative) and am familiar
with them.
Strictly for price....Polyrod is a winner
Strictly over the long term....advantage Philly
The problems with Polyrod......
1. It is more difficult to work with. Gloves are a necessity if you don't
want to pick splinters out of your hands.
2. Difficult to store. Two choices here...either you have an 8 foot hula
hoop or a verrrryyy long piece of Polyrod laying out in the yard.
3. Resistance to sunlight. In the Florida sun it started to break down
pretty quickly, with the outside becoming fuzzy when exposed to the sun. I
have
no idea how substantial the damage would become over a long period of time
in that or any other high UV area.
4. Difficult to transport if you ever move. You have to rewind it back
into 8 foot diameter coils (splinter city). That's not a lot of fun. I know
since I did about 3000 feet when I sold it all. Trucking it on the back of a
pickup to Dayton was interesting. Also when rolling the used stuff back up,
it looked as though it was snowing with all the deteriorated fiberglass
flaking off. No such problems shipping Philly to Hawaii when I moved. Roll
it
up, and put it in a box.
I have had some of the Phillystran I will use out in Hawaii for over 20
years. Other than having to spray the old fashioned potting ends with cold
galvanizing spray, they are in excellent shape.
Neither of the two fiberglass alternatives are particularly sturdy in regard
to abuse. Philly easily abrades and Polyrod if subjected to a sharp bend
will snap
In summary, my choice for non-conductive guys in order of preference:
1. Phillystran
2. Polyrod
3. 502s and short lengths of EHS. 502s are expensive, so are guy grips.
But, you will get lots of exercise twisting guy grips..good for the heart!
