I have used a Snatch Block that is heavy, noisy, and expensive compared to the ring. That little item is called a Shock, got it at WM. It makes a quick, smooth, point of attachment.All U Get.... I notice you have a small block at the base of your rig. Why not use a light weight block on the jib sheet also. What are the advantages of the ring?
I did a double and it held in light air. If it slips, I'll use a triple. I almost lost my snatch block in gusty winds when it opened unexpectedly. I don't think I'll cry as much if I lose this ring.Makes sense,,, light and inexpensive. Any problems with the hitch knot with the slippery dyneema line?
