For the hangers: ENO hammock Slap Straps (Slapstraps?) compare

Sounds like it's just a length/width difference? I've never used the ENO Slap Straps, I use two 6' polypro webbing straps from whoopieslings.com (similar available from arrowhead equipment and others). I find that 6' (72 in) is plenty for most trees.

Differences are what they've listed. Weight, length, and webbing width. I'm very heavy and have used both without issue, though not for backpacking.

Maybe this is a case of me not seeing the application implications.

Why would anyone want a shorter, heavier strap?

That is to say, do the "Original" and "PRO" serve different needs?

Yeah, use plain webbing for the tree huggers and whoopie slings for the suspension, ala Shug:

ENO straps are the devil's work. It's made of nylon which stretches over night. You need polyester straps not nylon.

I've tried lots of types of straps and eventually I ended up with some 100% pure dyneema rope (3/8") was rediculously strong (3,000lbs+) but it was light enough to float on water and had zero stretch. Its pricey but really nice. I've got a bunch of Samson bluesteel if anyone is interested. I suppose since this is BPL I'd better weight it before I say so, but I was thinking it was half the weight or less compared to nylon web.

Biggest downside was that it's only practical for hard barked trees or only use it on soft bark with vertical sticks aligned in the loop to prevent cutting into the bark since it's so thin when compressed.
