I would recommend a careful inspection of all the rigging when it is in your shed. Clean it all thoroughly and check for pitting, cracks, bends, hole elongation, or chafe. Dye penetrants can be used to check for small cracks. If any of these faults are present, I would replace. Often people neglect careful inspection of the other hardware when replacing rigging wire. Remove and inspect the mast tangs, bolts, compression tubes, etc. Take the spreaders off and inspect the supporting hardware. Rigging wire can last a long time if properly set up, tensioned, and cared for. A local rigger told me most rigs are lost from other causes than wire or swages.
