replacing rod with 1*19 wire

[Bryanj]

What is the cost differential between rod and wire?

Can rod be replaced by wire?

If so how do you make mast connections?

Is matching strength or stretch more important (rod versus wire)?

Will termination pins match (i.e. if the cap shroud ends on deck with a 1/2" pin would the 1*19 wire turnbuckle also use a 1/2" pin even though the wire has a larger diameter than the rod?)

Thanks,

Bryan
