My beef with that video? He was no KF Master. Not in any shape, way, or form. I watched that video and saw nothing resembling Kung Fu. Period. Worse? Read his website. He now refers to himself as "sempai", which is a Korean term, and teaches Korean styles! Combat Aikido. https://www.jasondelucia.com No way would I consider this gentleman a "Kung Fu Master". He used an obscure style to try and make a name for himself, and is now marketing himself as some Korean stylist.
