Most times when I use regular soft shackle I put on a sleeve of tubular webbing or the cover from a rope or cord between the stopper and the brummel for chafe protection. In order to open the shackle I have to push this sleeve back, that is one movement. Opening up the brummel, which takes two hands if the shackle is fairly short, is the second movement. Pushing the stopper knot out, while holding the loop open is the third movement. Not easy to do but also makes it hard to accidentally open. It could happen, but the loop would have to be opened and the stopper leveraged out of it. Definitely not ansi compliant by not being auto closing or locking but those are for carabiners and snaps. This falls more under the rope termination section.
When I rec climb I break the ansi rules, is that wrong? Would you no longer free climb a tree just for the fun of it? I don't do anything dangerous but if you use common sense it is safe to deviate from ansi.
Also, I will start out high and fast, er... I mean low and slow!
