I started off using his method, poorly. Don't get me wrong, his method is great, I just tied them poorly.
Ray's voice is totally relaxing too, like he could be under attack from some large animal and still maintain that dulcet tone. He's quite the knowledgeable fellow.
Enjoy the elevation
I had a bit of a problem with Siberian hitch - creating slack while tensioning it for the first time and later coming completely loose over time. I still don't know how or why it was happening, it's probably my own problem.
Now I'm using what was fancy here two years ago:
gathered end hammock (with webbing loops on both ends)
simple webbing straps with loops tied on one end
toggles (made out of random branches)
It needs no sewing or other skills, loop knot is trivial, marlinspike is really easy, almost doable with one finger. If something is beyond use - I can replace any piece with any piece of thicker cord until reaching first hardware store where I'll find all I need to recreate whole suspension. I found it to be really reliable and easy to set it up, break it down, replace or repair on the go.
I guess this setup was faved here on hammockforums before all this slings, clips and amsteel mess started, now the forums look more like advertisement board with brand names all over the place.
