Chris, sorry... Yagyu Shinkage Ryu. The KSR interest was fleeting, for both Sensei and I... It was motivated by an interest in history more than anything else. He had a video we studied from, and we bought the KSR book through Koryu... Certainly not the right way to do it, but there being so few real KSR schools here, it's one of the only options. He has since gone onto Shaolin Kung Fu, despite being a world class Iaido practitioner, because of the beating his aging knees were taking, (we are both in our 49th year). As far as me, having kids slowed and stopped my interest, revived only because of my son and his interest in Cuong Nhu this past January. I find their community to be very open and intriguing, with so many styles rolled into it. When I read O Sensei's story of escaping Vietnam, and his philosophies of love and community service, I was hooked... It all clicked at the right moment. It is very rewarding to be learning alongside my son, and I look forward to a demonstration we will be doing with our dojo at an upcoming festival... He knows the kata better than I!Mike
