First let me preface this by stating that I have not personally met either Doc or DarK Kenpo LorD, however from reading their post the I can say with some assurance that they are both staunch advocates and proponents of the Ed Parker American Kenpo System. This post is not intended to defend any one point of view over that of another, it is just my observations of the written word and my own interpretation.
DarK Kenpo LorD, it looks pretty clear that although Doc doesn't feel strongly about the extensions, he does not boo hoo your beliefs and actually states if YOU find value then by all means soak it up.
DKL, I have heard this from more than one of the "Seniors" & 1st Generation students of Mr. Parker. You can take a look here...
Original System It's is unique that Mr. Parker was actually chronicled about this.
It looks again as if Doc is not boo hoo'ing your beliefs, just stating the HE and HIS students don't find the value in many of the extensions and #2 sets for the way HE teaches Kenpo.
DKL, you have the fortune of living in the state that is the Mecca of Kenpo. Why don't you take him up on his offer?
