I don't know, Tom. I've stacked a lot of Rohn 55 and would not be comfortable
with 1/2" nylon at all. I recommend 3/4" Polydacron.
When Phillystran was Philadelphia Resins, they made a syntheic rope just for
use in pullys. I don't know if it still is made, but it was expensive. Bottom
line, as Tom said, Phillystran was NOT made for this application.
