I used cable clamps when I installed HPTG-6700I in the early 90's. This is
what Phillystran recommended and I recall someone on this list saying: "Do
what the manufacturer says". It worked fine until I moved the tower over a
decade later.

That was probably in the days before the Big Grips were available.
Using cable clamps on the Phillystran led to cold-flow of the aramid fibers
and a reduction in strength - a big problem. But you weren't tensioning
them
to the 400# you'd need for regular guys so your risk exposure was pretty
small.
