When you pull your mast for the season, have your yard pull the clevis pins and hand you your standing rigging (you label it first, of course). Put it in a box and mail it to Rigging Only in Fairhaven, Mass. They will measure and renew each piece and send it back for you to re-install next Spring.
Great service, great prices - highly recommended (I am a customer, not attached to the company). I had them do my main shrouds and backstay last winter - going back to do the lowers this winter.
