We have a dyneema/amsteel backstay on our fractional rig... we have a roachy main and use a whip to ensure the sail clears the backstay on light air gybes and tacks. (Wire would have been too heavy)
Some tech info here:

I think the generally accepted spare replacement for standing rigging these days is a coil of Dyneema - such as Amsteel.
UV stable; coils nicely and fits in anywhere; stronger than steel; splices easily as it's single braid!

gadnagit, spare rod rigging is usually carried by taking a section of rod and coiling it into a large coil. Yes, it is flexible enough to do that, and then stow the coil someplace. Of course you can also temporarily rig a repair with some bulldog clamps and a length of cable, as long as you have a suitable spare for the end fitting.
My impression is that rod rigging will outlast cable in comparable uses. Inspecting it will call for a dye-check of the end fittings and reswaging them is often possible if there's enough extra length (i.e .in the turnbuckles) to allow for that.
But NavTec themselves seem to prefer not to respond to customer emails at all. I tend to look askance at any vendor who can't reply to emails these days, it is no different from throwing out letters or not answering the phone. NOT professional or businesslike conduct.
Maybe as synthetics become more common, they'll just go the way of buggy-whip makers.

I also disagree that Fractional rigs require more attention but here I can also see why someone might say that. As a very broad generality, fractional rigs respond more to changes in backstay tension than masthead rigs and so the backstay is ideally adjusted as windsppeds go up and down. To some that may seem exotic or may seem like adding yet another thing to pay attention to.
But I see this a little differently. When I started sailing in the 1960's, yopu almost never made outhaul adjustments after the sail was up and flying. It was pretty much set and go. Boom vangs were seen as exotic. Today most cruisers would look at a boom vang as a safety item which should be aboard, and by and large, most knowlegeable sailors will adjust the outhaul to the conditions. It would be easy to argue that having a boom vang or adjusting the outhaul requires more attention, but to me these are tools which make sailing easier and at least with the vang, makes the boat a little more forgiving.
In practice neither rig is inherently less reliable or more prone to failure. The likelihood of short service life is much more dependent on the details of the design rather than the choice of rig.

As much as I like rod rigging for its lower stretch and predictable elongation characteristics, personnally I don't consider it as reliable as I would want for long-term distance cruising.

|captflood||GREETINGS EARTHLINGS ; try to find out how old the rigging is and what is the service life of same have it all checked out by someone who knows that type of rigging then try and get it all worn out GO SAFE.|

Most excellent responses, I really appreciate the input. This forum is great.
