Issues with synthetic rigging?

[Brion Toss]

Hi,
And thanks for the numbers. I can see that this might be an issue, but would like to throw in some qualifiers. First, the range, in rational measure, is from freezing to 86 degrees. Not likely to happen in a day, or in a given season. Next, the 15% tension you give for stainless is typical for long wires, like uppers and jibstays. Next, it seems to all depend on what kind of pretension the Dux would be set at. If these numbers are accurate, one could have shrouds at about 6% when slackest, and 12% when tightest, which would keep it under the worst creep levels. In my climate, this varying tension works out for stainless, as the winds tend to be highest when temperatures drop, so this could actually be a feature.
Anyway, looking forward to further documentation and analysis. And to the adaptations we come up with in response.
Fair leads,
Brion Toss
