I still like to use tautlines for my guy lines... But for the suspension the adjustability of the whoopie slings is just too convenient.

I use knots exclusively for my tarp.
Since my suspension is straps, I use 'biners and cinch buckles.
Being a single braid cord that is easily compressed to a dangerous level knots are not recommended by the manufacturer of amsteel. Amsteel is also very slick due to the type of rope it is and the coating that are added to reduce friction. Many knots have been found to slip. That along with the higher de-rating due to the compression and most avoid using knots. Splicing it is quite easy though and what it is intended for.Originally Posted by David

Also I might add, that we just love the fiddle factor of DYI'ing our gear, and using the ingenitutity of stuff being made for speficcally hammock hanging by our cottage people. Seems to me everybody is constantly tweaking their gear and setups looking for the absolutely best setup for each of us and so we are constantly experimenting especially on suspensions and tieouts when not hanging. Kinda gives us something to do as well when we are staring at all that equipment we spent alot of money on.

I was hanging from some braided rope about 6mm I thought it would hold my weight, so when it dumped me on the floor I was most embarrased but I was hanging on a boat deck the rope had been cut by a sharp angle on the rail I had tyied too LOL...
so I ended up here looking for better options :-)

Your rule of thumb assumed a thumb of a different length or thickness.
Climbers and arborists are around 12mm / 1/2" - 5/8" line with a BS that is +-20% for that size, so long as the material --nylon or polyester -- and construction are sound. Take polyester or nylon down to 6mm / 1/4" and the strength is reduced 3/4, assuming --as may not be the case -- that a same- thickness and weak jacket doesn't now account for more of the total heft, leaving a 3mm core to carry the load. Knot it, and the bs at the knot migh be that of a 2mm poly /nylon line, just 100kg /200lb.
The strengths you see listed from serious makers of Dyneema and Spectra based line, including Marlow in the UK, are all of properly spliced line. When cordage is that pricey, it gets spliced, not binned.

any climbing rope we use is one length because of the prusik type devices so splices are not safe. we also have LOLER inspections that would fail any home done splices too...

The Dyneema / Spectra cordage used here is totally unsuitable for climbing, except in emergency cordalettes / slings. No stretch and no energy absorption. Putting a jacket on just provides a grip.
Speaking of which: It isn't clear that the various coating have much to do with slipperiness of Dyneema / Spectra cord. In fact it seems more likely that the coatings reduce internal slipperiness, increasing stiffness, and make the cord easier to handle. This stuff is inherently ultra-slippery.

:-) no climbing on a whoopie sling would be a little silly LOL

I know all my knots but find myself drawn to the ease of use many of the alternatives offer. In my opinion, knots are better but becoming a lost art. I tend to like faster and easier (ok I'm just lazy).
