As I told you privately, the photo you sent me of your guy wire is not of
any EHS I've ever seen - it appears to be what we often call aircraft cable.
EHS is quite stiff and "whippy" - it will not lay on the ground like a rope
in gentle curves, but rather tries very hard to lay straight.  It also comes
in coils/spools of much greater diameter than comparable aircraft cable.

The 2 questions at the bottom of your post are confirmation, IMO, that you
fo NOT have EHS cable and therefore, PLP's grips cannot be used:

1) Most EHS (ALL that I've seen) is left hand lay and that's what the grips
are designed for.
2) EHS is made up of 7 solid strands, and not 7 strands of 32 wires each
(for example) so the lay of the strands vs the lay of the wires is not an

I suspect that if you believe that "most wire rope types are right hand
laid" that you have never seen the type of EHS we are accustomed to in the
