I’m currently participating in a JKD class in So Cal. It is heavily influenced by eastern yoga type philosophy and Tai chI. The FMA aspect is still there, but heavy serrada influenced. There is also a heavy emphasis on the “inner healing” and “energy” which comes from the eastern stuff. See Sifu Singh type of teaching philosophy. At the Kali academy we learned from the ground up. Here they kinda teach from the middle out.
I took the semi traditional JKD ala Inosanto / Lucay Lucay back from 79 to 90, so this is current iteration is really foreign to me. The modified wing chin is there, but it’s a long way away from what old timers would consider JKD. Whatever JKD means….
