I was under the impression that the change to the name Soo Bahk Do was made more to distinguish the USTSDMDK from the many off-shoot TSD organizations that have sprung up over the years (I may be wrong though...). Does anyone know whether or not the Soo Bahk Do organization still uses the older base forms (i.e Pyung Ahn, Passai, Naihanchi, etc...). When I left in the early 90's they were just rolling out the Yuk Ro hyungs... At that time I thought they we were just expanding the curriculum to show more of the chinese influences... However the wording of your post makes me wonder if the intent was to eventually do away with the Japanese influenced forms... to answer your question, yes, Soo Bahk Do uses Pyunk Ahn (I believe 1-5, don't know the exact number because I haven't gotten through them yet, but I watch others do them in class), Chil Sung 1-7, Passai, Naihanchi (sp), there are also other advanced forms as well as some specific weapons forms. I don't know if the weapons forms that are taught at our dojang are considered "standard" (by the US MDKSBD federation), but I believe they are, but don't hold me to that .
