Rx,
I changed out my LL's two years ago. My boat neighbor with a beautiful re-done Morgan 44 replaced his with 316 stainless steel, not the 304ss grade.
I do believe the run-of-the-mill coated lines are 304ss (too much carbon in the mix). The 316ss lines I have also is bare & has no pvc/vinyl coatings. I did move up in wire size based on my stanchion pass thru eyes. The non-coated lines are smooth to the touch & I find very appealing to the eye. No more having to see coatings get dirty, rusty (304ss), discolored or crack over time. Riggers have both grades.
Just some food for thought as I use 316ss for all my rigging.
