I am wondering if anyone familiar with the Palgwe patterns could comment on the variations that seem to exist from one organization to another. For example, after learning Palgwe Il Jang, I found on youtube at least two variations. I learned it where all of the middle level blocks are performed as an outside-to-inside block. I've found at least one video of someone performing it as an inside-to-outside middle block. Here's a good page to illustrate this. The top video shows the way I have learned it: http://www.taekwondoanimals.com/taekwondo-palgwe-1.asp I am wondering if these variations are the result of an "old way" of performing the form versus a "new way." And if so, why the change?
