I've posted it in other topics, but don't see it here - the Python straps and Atlas straps had about a 5 to 6 inch loop or "step". Before I switched to Daisy Chain from Dutchware, which was lighter and had a 3-inch step, I made a 6-inch Amsteal loop that I could fold over in the Python or Atlas loops. It would give me a 3-inch step.
Note that if you have a structural ridgeline on your hammock, that step distance isn't so important because the ridgeline keeps the hammock at your preferred sag distance. And if your hang angle is a little flatter than 30°, the stress is transferred to the Amsteel ridgeline, not the stitching on the hammock.
What is Amsteel? You could call Amsteel "woven rope". It's available in many Marine supply stores and from online hammock vendors. A common size is 7/64th inches. Using tools like a small knitting needle to open the weave, you can make a variety of useful accessories (loops, dogbones, whoopie slings, UCR's).
What is a structural ridgeline? If your hammock has a built-in bugnet, it already has a structural ridgeline that limits the distances between the ends of the hammock when it is set up. That way, you don't tear the bugnet, which is sized for the hammock hung at the 30° angle.
If your hammock doesn't have a ridgeline, you can make one. First, you need to find the "sweet spot" sag for your hammock. Then measure the end-to-end distance and, using some cord, make a line that connects from one end of the hammock to the other - effectively a long measuring stick, except it's cordage.
You can leave the cord on the hammock permanently or remove it once the hammock is hung. You'd attach one end to your tree, then the other end, so that the line is just snug. Of course, there's an adjustment for hammock height above ground, etc. So much easier to show than describe.
What makes is "structural" is that if the cord (7/64ths) is made from Amsteel, it will hold over 1000 lbs. So the link from one tree, to the hammock's connection loop, to the ridgeline, to the other hammock end, to the other tree, will clearly hold your weight. And you can relax your attention to the hang angle just a bit (if shallower than 30°) because the Amsteel can deal with the stress.
If you use a weaker cord, even just string, you can still use it as a long "measuring stick". Attach it to the hammock to get the end-to-end distance right, hang the hammock, and then remove the cord. Because it won't hold much extra force, unlike a structural ridgeline, you'll want to keep your hang angle as close to 30° as possible.
