Thanks for the video! What is it about that setup that makes it easy to jump into the actual triangle position, rather than him having both his arms up and it just being a jumping closed guard, or both his arms down and this becoming a jumping...nothing? I would have expected a flying triangle setup to be some way of getting one of his arms down and one arm up so the triangle position becomes easy, but here you're just snapping him down.
I know it works for you (absolute finals at purple), but do you ever end up just regular jumping closed guard with this setup?
