One "miss" with the Origin steps is that the full bury 7/64" amsteel hitch becomes a larger diameter and firmer than the 1/8" amsteel it slides on. This means it does not grab as well as it could.
Mine came with the hitches all different lengths and some were so small that the metal piece that locks it was difficult to insert, even after doing the stretching they recommend. So, I bought a splicing loop and remade all the hitches and they are all now uniform and the loop is a size I like. I stretched them all much more than the video shows by creating a loop not on a tree and then hanging from it with full body weight (about 190 lbs with clothes/shoes) until it stopped stretching. I actually used a stool and stood in the loop.
However, in an application like the hitch, you could get away with making the hitch out of just 7/64" amsteel (no bury) and then where the schwabisch hitch crosses over (that piece that is straight and goes across the loops that do work) just tie 2 overhand knots. It will likely grab better. People reflexively say never to knot amsteel, but in non-life support settings (if a step breaking will kill you, you are climbing wrong) where very little force is seen and it is static, then it works fine. You just have to tie a knot that will not slip loose due to the slickness of the amsteel. I have made amsteel aiders using knots9 carefully and used them for many seasons and there was never a single issue. There are resources online regarding knots that will work with amsteel. If you can somehow break a knot of 7/64" amsteel in this application, then I'd be shocked.
