Bruce's concept was actually to cross train and not be someone doing an MA, just do what you needed to do - he had a much more pure vision
it's the people who tried to turn JKD into just another MA system, the opposite of what he said to do, that caused the later confusion
Gracie's wanted a system that would work for them against any opponent - the fact their "their" MA became something that people who copy and distort later on is again against the original vision
Neither Bruce or Helio wanted any MMA style, that was not the point they were working to get across
Anyway, what we do is go back to the original ryu and use what we know worked - when we do KH as LRA it is taijutsu of koshi jutsu and comes form Gyokko ryu which itself is rooted in chinese kempo
so when we do kempo later, we are not doing a different "art" or mixing arts to create something new as if we were making a cake from a recipe
when you are drilling sui and ka no kata and it's similarities to the sword techniques of kempo, or how Five Swords is six count of kali, it's the common thread you or working on
Five Swords also works with elbows
a thai elbow
a kali elbow
a karate empi
you are not mixing but flowing
