If I recall correctly there was a time between potted ends and Big Grips that 
wire rope clips were recommended for Phillystran.   I had a few guys like this 
on my Rohn 65G tower while in Chicago.  I still use wire rope clips for 
Phillystran boom trusses usually HTPG-2100I pr HTPG-4000I.  Yes it crushed the 
cable but I have yet to have an issue with the Kevlar fibers plus using a Big 
Grip would defeat must of the purpose for having a non-conductive truss.

Having been using Phyillystan for a couple of decades I would certainly NOT 
advise using any kind of compression clamps.

You would be crushing the Kevlar fibers which is where the strength is.
The preforms are not only the manufacturers recommended but they are not that 
expensive to do it right and above all safe.
Is it worth it to do it right.

Yes. Tighten them all the way down. It really squishes the Phily down.

Used 4000 lb Philly on a Rohn 25 without preform grips. Worked perfectly.
