backstay insulators for galvanized rigging

[cwa]

I was wondering what would be a good choice for backstay insulators on a galvanized standing rig?

All commercialy available insulators that I've seen are made for stainless rigging.

I have been thinking of using short lengths of 3/8" Dyneema or Vectran with eye splices & thimbles on each end and the galvanized wire running between them.

My rig has two backstays and only one would be insulated.

Thanks,
Carl
