Much appreciated, thanks Jim and Matt!

In my own curiosity, and by being at home with spare time instead of being on the boat, I combed through my photos from the last month and I think I can find evidence that this strand has been broken for at least two weeks. Glad that it didn’t break further during last thursday’s weekly race 10kts puffing to 15. Lots of tension and backstay for our double-handed team.

Now I’m at the crossroads of replacing with the original spec stainless wire, or beginning the transition to Dux. One design isn’t a concern, but I’m sure there are some opinions out there on steel vs plastic!
I would rather be able to visually inspect my rigging and be able to replace it myself should something fail.

Stick with the 1 x 19 stainless steel wire. Proven, easy to get and good longevity.
