Galvi rod rigging?

[benz]

Has this occurred to anyone else? I'm still researching rigging options, and it seems that if SS rod rigging is superior to SS wire, why would galvanized steel rod rigging not be even stronger and less elastic than SS rod, and cheaper, and easier to inspect for rust than wire, and not given to crevice corrosion?
Has anyone used or seen anything like that in use? Pros and cons?
