I was hoping to find some older generation CDK masters to establish contact with...
(Many years ago I was taught by a really impressive CDK master, and some of his technical training was slightly different from the now standardised Kukkiwon style - but effective. Hence my interest in CDK)
GM Park, Hae Man is essentially the "public face" of the CDK. He continues to travel all over the world doing seminars and attending dan tests.
Also, does the chung Do Kwan - and GM Park, Hae Man - do anything notably different than the Kukkiwon technique wise these days?
