Solid welded links are probably stronger than screw links, if less convenient. I'd agree with Sway that holding a load up by two essentially horizontal lines is not a wise thing and quite dangerous. The forces involved are quite significant and unless you're really aware of them, you're going to get someone killed. His point about the loads being enormously magnified by the lines being so close to horizontal is one you have to pay attention to.

This is kind of why I was wondering what your purpose for the rings was.

Just for yucks and giggles, take some small stuff, say 1/8" rope and try lifting a 50 lb. weight so that the two cords are horizontal as you've indicated you want to do. I know a 1/8" rope will hold 50 lbs. pretty easily, since the stuff I use has a breaking load of almost 450 lbs. I bet the rope breaks before you can support the 50 lb. weight with the lines almost horizontal.

I'm starting to think that screw links like the ones that climbers use might be better able to hold a load instead of something round like a metal ring.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
