what helped me with scissoring was learning switchups. I couldnt scissor before I could switchup, but once I could do switchups then for some reason scissoring came naturally for me and I could feel it better
That's the thing though. I couldnt scissor, but then I started doing some front swaps and while learning that, the scissoring came naturally. I don't know.. Maybe it's just me
There's just about no way that you could stop your motion like that on a rail without gripping it, which would require scissoring, except absurd levels of abdominal strength.
