Probs a bit too late to comment, but we went with Coligo dux rigging back in 2018 when we had to swap out our old rod. (Had a rod head failure and nearly lost the rig in the last 70nm of a 500nm passage) total price was $4000 ish for everything. All new turnbuckles, and new cheeky tang mast fittings. The quote for new rod was more, and shipping a 4'x4' box to Tahiti was very cost prohibitive.
Replacing with 1x19 wire was nearly the same price, but my friend who had a new wire forestay fitted on his dufur 455 in Tahiti lost his rig just before arriving in tonga when one of the swages on that new forestay failed. (Be wary of Matt rigging in Tahiti)
We then sailed from Tahiti back to the Tuamotus, again to Tahiti, then on to the Cooks, Nuie, Tonga and on to NZ. We are still running on that dux rigging on Cinderella. We maybe motored 5nm during all of that, so nearly all those miles were done under sail.
My review: its awesome, haven't had to adjust the shrouds at all since we did the tune before we left Tahiti. I recently got a quote for new dux rope here in NZ to replace the full rig, it was $900NZ. Rod or 1x19 wire is considerably more and you need a swaging machine or expensive fittings to repair it. Dux can be spliced with basic tool anywhere, and the boat acts like there is a 200lb person on the rail at all times, it just stands up better. We could wear the dux rgging as a necklance its so light. I intend to keep a spool of 9mm dux aboard for any emergency splicing when I head back to the tropics.
I do plan to replace the rigging before we head north to Fiji to duck the kiwi winter next year, and I will cover it next time to protect from the only slight wear we are seeing (the jib sheets rubbing when tacking or hove-to). I will cover it at least to the first spreader (probably completely) and that issue will be resolved.
When I start to see it stretch, it will be time to replace it, pretty great to have a tell on when to replace it. The same cannot be said of SS rigging. Even at 50% of its break load its stronger than the SS wire that we would have used.
We are not sponsored by Coligo or Hampijdan but very happy with the product overall. If you do decide to use Coligo, let me know as I do have a bit of advice for ya.
