I may be late to jump in, but here is my 2cents...

On my TheMightyHobie18, I wanted my rigging tight, and adjusted my port side stay every time I went out (since the furling jib is limited to how tight you can pull the forestay).

After having my pins and rings catch and bend on my shorts or trap bucket all the time... and forgetting to adjust it and making "on the fly" adjustments (while underway), I switched to ALL shackles.

This was expensive and probably not all that needed.. but it gave me piece of mind, and I didn’t curse out those little rings that pop out of my hand, into the surf or sand... never to be seen again.

I also had a near disaster one time with a quick release that came out (i wont say what it attached) as I was tacking and right near a sea wall… in 15knots… my crew fought with it and was able to re-pin it at the last second…

Amazing how 1 pin can determine the life expectancy of your boat… I again switch that to a shackle and will not look back.
