well this is where the probelm is. I believe JKD is an MA and a concept. There are specific to jkd that make it jkd. I'd argue that their aren't forms or patterns, certainly not in the karate sense but if you mean in the sense that a boxer will practise their punches and particular defenses then yes we have that.

You could apply jkd concepts to your MA but to me it wouldn't make it jkd.
