Figured I would make a new thread to keep this stuff together. QRC is the Ultrasabers quick release coupler. That is a nickname given it by Ryan who has been rocking one for a while now. Figured I would make a p-lace to discuss the thing and how it works. I posted a longer video before but this one is my second day of practice with the thing. I am still a bit shaky on the reconnect, but getting there. As far as I can see, there are about 4 ways to disconnect it effectively and 2 ways to reconnect it effectively. For me at least, reconnecting in motion always requires at least one hand in reverse grip. Also worth noting, one of my viewers who also has one suggested that a piece of a yo yo friction pad at the base of the inside part removes the play and spin in the coupler.
