Try 3/8″ mainsheet line sold at West Marine or a similar place. It’s rated high enough for hammocks, is very low stretch, and is available in white. (I like line I can see at night.) I used mainsheet line with SMC rings all summer (2022) without problems.

Thanks Ted. I’ll have to give a single turn a try. The double turn works better with slick cord like Amsteel. You can find Spectra cord from rope climbing stores, including REI.

I’ve been using a Hennessy ULBP for years and have tried a number of suspensions. The Garda Hitch with two SMC rings is by far the best I’ve found. I noticed in your guidance that you use two turns around the rings before passing the line between them. I’ve been using one turn with no problems but decided to try it with two. The sheathed Spectra I used locked up tight with two turns and was difficult to undo. I think it’s because the sheathed Spectra grabs a little better than the slicker Amsteel. Anyway, I’m back to one turn with a safety half hitch.

Also, can you recommend a source for replacement Spectra? Thanks.

I don’t know if you’ve tried them yet but I used my GM rings last night and they worked great. Hope this helps.
