Brion,
I'm curious what if any weight you ascribe to the maximum peak load as determined by Jordan? I wouldn't quibble with 3:1 but I could also argue that 10;1 would really be proper.
It's also worth noting that current best practice is to use dyneema for a JSD not nylon. The reduced stretch helps keep chaff down, and the minimal stretch actually reduces shock load since the entire drogue picks up loads more evenly with less delay between when the first cones start pulling and when the last ones do. It also prevents the boat from accelerating down waves since load is applied much earlier in the wave cycle.
Of course this also means a smaller, lighter, and easier to handle unit, which is always nice. And on a price/MBL dyneema is actually about the same price as polyester. Of course it does demand splices instead of using a cleat, but that isn't a huge deal.
