This is nothing more than my personal opinion, based upon your interest in continuining your Hapkido Training. I have reviewed the ICHF Master level DVD's and in all honesty, NOT IMPRESSED!....
The mindset that is offered, I agree with, but the technique offerings are somewhat questionable (mpo). In order to use the term "Hapkido", I believe that Mr. P had to offer something different, than what is already being taught, just change for change sake. Otherwise there would be no real need or justification for the assignment of a "new kwan". I would suggest that your initial review of past history here at MT, regarding MR. P and the ICHF did not go far enough back. Perhaps another more indepth search may offer a broader scope of information / opinions on the subject.
While I don't consider myself to be a died in the wool traditionalist, I do have reservations when dealing with, what I consider, questionable training material.
I realize that there are folks that have great zeal for what the ICHF offers and some even have some formalized Hapkido training, prior to joining the ICHF. I confess that I have to scratch my head and ask why, but it seems to sever their purpose and in reality, that's all that matters I guess.
