I just ordered 4 from REI. Looking forward to the ease and simplicity of this system (as well as the weight....I hope :))
I think this is the one I used, but the page has changed and it no longer lists the internal diameter. Mine are 1.5" internal diameter.
Just made my ring supports yesterday using 1 in. webbing off of an old ratchet strap. will post pictures later.
To keep this going.
I had 2 hammocks setup last weekend, one for me and another for my dad. They where exactly the same. He hung his and I hung mine. I got in mine with no issues and he got into his. I used a slip knot and he did not. Both of us were moving around in them. I later got in his and hit to the ground.
I weigh around 220 and he is closer to 180. That was the only difference in both setups. I think this might help to explain why some get slippage and some do not. I think the extra 40 made all the difference.
I weigh 160lbs. and have never had any slippage issues. I've wondered if someone much heavier would have more slippage problems.
