So you have experience with SS rigging. You even have the tools. I faced the same decision with my Mac 26D. Even bought 3mm dynema. Looked up techniques ( all for much much bigger yachts) and would have had to adapt a fair bit. Ultimately I came to my senses and gave up on the idea. There’s no real weight savings that a cruise like me would realize. I don’t race anymore so there’s no competition to scare with a new supposed go fast. Bought nice SS cable, thumbs and nickel coated copper swages and used my hydrologic crimper. Never regretted the decision.
