I read through some of the comments about sound quality and filler words and, yes, I agree that sometimes the audio quality isn't there and I am certainly in no position to comment on "ums" as I can use those more than anyone! But one of the great things about podcasts is the accessibility of creating them by anyone with a microphone, a computer, and a topic to talk about.
But the content of the podcast is enjoyable and, as a fellow karateka, I really appreciate that they don't try to diminish the other martial arts. In fact, they occasionally refer to training themselves in other arts. The hosts come across as genuine and, although obviously knowledgeable, are also still open to learning and hearing differing opinions. That's not too common these days.
Only complaint? More regularly released episodes! Keep up the great work!
