Galvanized 7x7 wire to be used on traditional brig

[Kalu 1957]

Hi, We are rerigging a small 1930 iron hulled brig, that has had an aborted assemblege of non matched, various diameters and aged stainless steel wire mixing swaged, non swaged compression fittings and spliced ends....I'd like to redo her to accomplish a solid "period" look, frankly anything is better than the mess that is on the pallets in the building. Research looks like galvanized should be fine as certainly we are not looking to be a high tensile rig and with her spars also set up with steel ratlines sharing the standing rigging role i'm asking if you could see any major reason NOT to use proper yacht standard galvanized materials. Also are there any special care needs for galvanized in the clamping and end finishing process that would differ from stainless. The yards rigger appears to be VERY negative about galvanized...but then he was also bummed when I made it real clear I wasn't going to be putting 3 roller furling rigs aboard her forestays..... Your thoughts? Thanks ever so much!
