I bought a pair of the dyneema racer slings to use on my DIY hammock b/c I suck at splicing. I larksheaded a cinch buckle on each one then ran it through the end channel and ran the buckle through the loop. I imagine that's the way they do it. Does the same thing as an Amsteel continuous loop. Works like a charm.
But that's kinda the problem. The slings are hyped on the website as something akin to a Wonder of Science, but all it is is doing something exactly the same thing as most other hammocks but with a similar material.
The thing of it is, hammocks don't require a degree in rocket surgery to figure out. Most of the hard work has been done a long time ago: ridgeline 83% of length, 30* hangle, yadda yadda. The number crunchers have crunched and all we need to do is look it up.
Its a parachute cloth hammock with a top notch marketing department behind it, but they're really not marketing to HF members, they're marketing to first time hangers who are eventually going to find out that you can get the same hammock from ENO for half the price, or a better one from Hennessey for a few dollars more, and that Warbonnet makes some really cool stuf that makes Kammock, Byers, TTTM, and ENO look to you the same way your bicycle did the day after you got your driver's license. Either that or they are buying a hammock for completley different uses than what we here use them for, like hanging on the patio, at the beach, or in the back yard.
True innovation is what Dutch has done with teeny tiny widgets and do-dads that do amazing things, show that a lot of thought went into developing them, and that they were developed from personal experience.
