Many fine bushcraft experts suggest NOT using 550 paracord for hammock suspension. Many believe that while it's strong enough on it's own there is simply too much stretch.
|paramax 1000 and 550 paracord|
I tried paramax 1000 by itself and had a number of problems. It would have been a convenient solution but the knot on the tree side fused with the working end and took effort to remove. The rope stretched and was near impossible to get a consistent lay. Finally I added tubular webbing to protect the tree and that just made it bulky. One other attempt included doubling the cord and while that distributed the stretch it was heavier and bulkier. All that was important as I was planning to hammock over water in the everglades.
Good for guy lines but not much else. Black hard to see. Very think, and strong, could easily cut flesh.
Whoopie sling and soft shackle is just plain complicated and still requires something to go around the tree. All this joinery can be risky. The reflective material was chintzy.
I tried singular and tubular webbing. The singular webbing fused just like the paramax. The knots also slipped. The tubular webbing was heavy and bulky although it did not fuse. However, it was slippery and the knots did not hold.
The Yukon suspension system held up nicely. It was much less bulky than the ENO Atlas and the Yukon cinch (not pictured) was even better. Both held the suspension, did not slip and while the cinch version was easily adjustable the segment model was fast. I would recommend a Dutch Hardware webbing hook to prevent the material to material abrasion.
While the packed webbing looks like they might be the same size. The Yukon version is lighter and actually smaller by volume.
One unrelated item is my rope and s-biner to hank my pack from a tree.
