These straps seem to have the same easy design of the slap straps but are made out of polyester instead of nylon. I for one still use the slap straps because I love the ease of just putting the straps around the tree, unpacking my hammock, and clipping the carabiners into the straps. No toggles, no knots, no major adjustments needed, and even if I do want a different angle I just move the carabiner, takes 2 seconds.
I believe I will definitely be picking these up, and will probably post a review when they ship out. But I was wondering about other people's thoughts on these, or at least the 'daisy chain' style suspension system?
