I'm advocating the traditional usage of karate,not customs (i.e Karate Gi ,1936),as a total combat system.
I cannot argue with your statement above. In fact, I find your definition of traditional karate rather clever and tasty. You place emphasis on function (use) and not on empty form (customs). That said, I continue to believe that the usage to which you refer is de-emphasized for whatever reason(s) in most traditional systems. I'm reminded of a great comment made by Bruce a while ago: being proficient at sword making doesn't transfer into a proficient sword user.
Thanks,
