Dat's a hard question to answer. I'd have to rank several together for a 5 way tie. Shihan Everett Rodriguez of Yasashii Do - watching him move around our two toughest Black Belts like they were nothing when I was just a newly promoted Orange belt scared the hebedejeezus outta me. SGM Chuck Sullivan of the IKCA - Watching a 70+ year old man move the way he did was a testament to the fanatical approach to the basics Mr. Sullivan has. Doc Chapel of SL-4 - *Tap on da cheek.* Nuff said. - Although watching my buddy get tapped was infinitely more enjoyable cause I got to see what I probably looked like hehe. GM Vic Le Roux - Watching him rip on his assistant instructor at the WCKCII in August 05 was fun. Master Armando Deloa - IKCA - That was the first time I'd ever seen anyone move like water. He was taking down people who were 6 to 8 inches taller than his 5'8" frame with ease and the fluidity of his strikes, locks, sweeps, and finishes left my jaw on the floor.
