First, Jake thanks for the amsteel stretch notes I'll re-splice to accommodate. If you leave the bottom splice adjustable you can account for this in time

Karl, the dog bone works well and I think is a great option for skippers primarily buoy racing and single-handers. For a distance racing setup I like the adjustable setups. Gets my butt out of the waves, and lets me trap lower than a dog bone setup ordinarily allows as crew. Less critical for the helmsman but the crew ends up on that wire too.

I went with 4 separate lines. More difficult to manage for rigging but the splicing was easier. We have no covers at the top for chafe but am curious what others are doing. I might slip some on since I grabbed a bunch of scrap the other day.
