Ed Parker was the most generous man I knew. he would go anywhere anytime to talk "kenpo" with people. I remember going to different high schools that had clubs with 5 or 6 guys and he would stay for hours talking and answering questions, but he wanted the conversation to be productive. He was a professional, and when you came to him and into his business and asked advice he expected you to listen. A lookey loo to him was a guy who spent a month here and there trying to make up his mind about something he doesn't understand. It's a paradox. Sometimes you just gotta jump in and stay. Sometimes you get lucky, sometimes not. Comparing arts is not telling you anything but about the art. Ultimately it's the instructor you have to bond with. A lousy instructor in a good art gets you nothing. The only way you're going to find your instructor is to go look.
If you went into an auto mechanics shop and bambarded him with question after question and no matter what he said you just re-phrase the question, sooner or later the guy is going to say, "You want your car fixed or not?"
Some of the guys here have been really nice to you and taken their time to really give some good detailed advice. Apparently you have done this at other sites too with other arts but you simply ask the same questions over again with a different spin. In my mind there are some people you just can't satisfy no matter how you try in this medium. I suggest you go back to getting your information from personal contact where you can express yourself better and an instructor can "demonstrate" his answers to your satisfaction.
