Rope length for an Ultra Sling

[dmonn]

I want to make a 9 ft Ultra Sling from 5/8" Tenex Tec. How much rope do I need? Can I splice a couple of X Rigging Rings on the "loose ends"? I would use them doubled (side-by-side) to avoid an unbalanced load on just one side of the ultra sling.

About 26' to do that. Going to depend on how much rope you need to splice the rings on the tails, and how big you make the loop on the other end.
