It makes perfect sense. It all comes back to aliveness in "training". I went through much of the same thing, as I used to train very traditional TKD. Later I worked o boxing and Muay Thai and the difference in training was frightening, and very eye opening. However, how do you train for functionality, and still keep the pure tradionalism, and can you? Personally I dont think its possible, but Im not a purist either so it doesnt bother me like it would, say a traditional karateka or judoka
