I got
insanely lucky. TSD was my first style because it was what I had in my small hometown, but the instructor was this bad ass former Korean special forces sniper dude, and his curriculum was TOTALLY rogue. When we went to the regional black belt test all the dozens of other schools were doing the required curriculum which was super lame step block punch or whatever and we were doing full speed shoulder throws on hardwood floors with no mats. He had five blackbelts in various styles and was a former pro fighter, so we incorporated a lot of grappling and boxing and what not. One of his former styles was TKD so we learned that crazy spinning shit. He just never told me it wasn't necessarily practical, and thus I landed it on some dudes face in my test.
