Transition (high to low)
Seat circle forward to low bar
Pike swing forward to low bar
The seat circle transitions are kind of cool skills and, rated at C, not completely worthless or unnecessary. I’m not saying the top bars workers would use them, but most bars workers around the world are going to be counting some Cs.
The problem is more that they don’t really fit into the kip-cast-handstand-skill-skill-kip-cast-handstand context of modern bars routines. Especially the first variation, the pike swing one, has a sort of forward-backward swing inherent in it with is super verboten.
