LB, dudebro, I've done Kendo and Iaido. I was a member of the Midwest Kendo Federation. So, I appreciate you referencing them, but I don't have to watch any matches, as I was in them for more than a couple years. On top of that, starting at 6 months into my career I was pushed into tournaments because of my speed. I was faster than anyone in the tournament halls, to the point of being matched against people at my teachers' ranks. Granted, my technique was sloppy and I didn't score a single point against those guys/gals, but that's who I was put up against. Detroit's resident 8th Dan Sensei, Yoshiteru Tagawa, commented that I was the fastest student that he had ever seen. He called me "Hayabusa-kun," and made fun of me because my last name sounds very much like "turtle" in Japanese. (My teachers, Yutaro Matsuura (who is now a 6th dan!) and Dave Christman, came to me after the tournament and said, "Tagawa-sensei laughed at us because 'your turtle is a falcon.'") I know exactly how fast Kendoka and Iaidoka are, and I miss being that fast and faster. Curse you, injuries and age, for stealing my speed.
For reference, I've also trained extensively in backswords (Saber, Falchion, Scimitar, et al,) arming swords ("long swords", katzbalger, et al,) and greatswords (claymore, Kriegsmesser, großes Messer.) I've been fighting in various styles for 12 or so of the last 15 years, although I've fallen out of training due to injuries.
tl;dr: MZ really likes swords.
