Thank you for the welcome!
No, I haven't trained with either of the Lamkin brothers, but I certainly would like to. I have purchased a few of their products:
The Library of Kenpo: Awesome resource! When they mailed it to me, it came in a couple of boxes (I think it was a couple of boxes; it might have been just one decent size box). The Orange Belt manual alone was easily a couple of hundred pages. Lots of detail: Principles, What-If considerations, target areas and effects, ect. Each belt level was like that. I still have my Ikka journals (yellow-2nd brown), but the Lamkin bro's Library of Kenpo is by far the better resource (IMHO).
The Rapid Review Vids: Incredibly helpful. There was a period of time lasting about 2 years when, because of my occupation, I couldn't train regularly. These vids helped tremendously.
Family Roots and Master Key vids and guidebook: Very good resource. There were a couple of times that this series mentioned concepts I hadn't yet considered.
A few months ago (I think it was a few months anyway
) I purchased the Library on CD-ROM. I'm very glad I did! It included the rapid review manuals for both tech. and forms.
All in all, I'm very impressed with the Lamkin bro's work, and I would train with them in a heart-beat if I had the opportunity.
