I agree with the statements above. When I was one sticking, I preferred a short stick for packability. A short stick with a single step aider gave me full length stick function, in a smaller package. The statement about where the top step falls in relation to your leg, like hooking the top step behind your knee while standing is definitely a good point, you want your method to be comfortable. The cam cleat isn’t required by any means, I did it with a cam buckle and rope mod pretty easily, but I could see the cam cleat being the same difference in a prussik and Ropeman. With that said, Muddy sticks are popular for one sticking because they have a lot of key features to make it easier. Short length, cam cleat, and double steps. Muddy are a touch heavier than some, but if you’re only carrying one, it’s fine. I have cut down LW sticks and I don’t care for one sticking with single sided steps, not impossible, just not as easy or comfortable. If I’m gonna one stick, I’ll still rather take my steel DIY 20” double step stick I made that’s about 3-4lbs.
