Finally got some footage of this flip. I hadn't done that flip in several months but I guess it was okay. I still have an unstable landing and not enough height.
It doesn't hurt. Even if I would land on my back I wouldn't feel much pain. The floor was a bit bouncy and I'm used to falling. Pretty much I know how to fall correctly so that means that I never get hurt by performing any kind of moves. Only incorrect landings exist.
