Barb Wire Selection - high tensile vs low carbon and coating choice

[case580c]

I am on the coast and am can't decide of which wire would be better to stay looking good and not rust As the oceans salt air will rust Red Brand class 1 galv, in a few years if not sooner. I am going to use the 2x4 horse fencing Just don't know if the Bekaert ZA HI tensile with ZA coating or the Bekaert Horsemens with the Class 3 galvinized is the way to go

I would like an update if anybody has any on this subject, I have several miles of fence thru both timber (falling trees) and hills and flatland that I am going to replace. The green stuff sounds pretty good to me.
