Stainless Steel Utility Wire - 6 ft. of .020 inch (1.83 m x 0.5 mm) mil-spec grade, stronger than brass, won't get brittle in frigid cold, multiple uses
That converts to 24 gauge wire if my conversion table is correct. So referring to the OP, I'd select Option 3 - Stainless Steel 24 gauge wire - 17.5 ft. It will require the same amount of real estate in the kit as Option 1, but will be more durable.
