Jax---LOL I have a similar story, I moved from MD to MO due to a job relocation and there are no Shorinryu dojo's here (well there is but it's junk) so I tried TKD. I went in of course as a white belt. The instructor new I had a ma background, the students didn't. He wanted to see what I could do at the end of class. Normally they spar for the last 30 min or so. The whitebelts didn't usually spar, but he put me in. (Paul Dexter is his name, two time world tkd champion) Anyway, I didn't get tired until I was fighting the black belts, they were simply QUICK. All of the other 15 million belt colors were astonished because they immediately got cocky and wanted to show off a little to this "white belt". As soon as they threw that first high flying hollywood kick at my head, they realized I had a lot of experience. They would say "uuuhhhhh, do you have a MA background or something?" My response was always, "Yes." and nothting more I waxed all the others and in my eyes, i beat the blacks also. BUT, my major problem and why I stopped going was because of my background, I wanted to trap their leg, or grab their arm. I was tossing the blackbelts onto the ground and landing on top with an arm bar. Of course, this is all illegal in TKD. It was basically poor self control on my part, but I couldn't see changing my style, it is very effective and I love it. Ok, enough bragging.
