Thanks for that www.usmta.com
-- I just skimmed throught the portion of the site on KK and enjoyed it very much. The Ajarn Jason Webster mentioned therein was Salty Dog's first KK teacher and Salty received his rank of Ajarn from the Buddai Swan Institute discussed in this site. Any description of KK there would be far superior to anything I could write.
Grand Tuhon Leo Gaje's Pekiti Tirsia Kali is an excellent and highly influential FMA system which is the core system for Top Dog, as well as being a core system for Sled Dog (the highest ranked PT man in North America) Tricky Dog and others. I am a member of the PT family (accepted during my training in RP with GT Gaje) PT is a major influence on my core system (Inosanto Blend) as well as on Lameco Eskrima (the third of the prionciple FMA systems upon which DBMA draws).
Over the years I have learned to be very cautious about entering into "differences and similarities" conversations-- it seems to be very easy to step on somebody's toes when saying "X is this and not that"-- and one winds up having to write like a lawyer -- yech.
So instead allow me to briefly describe KK's role in DBMA:
KK is primal and power crazed and has many drills that are extremely simple which allows for primal, power-crazed training. This is excellent for learning to hit hard and to block hard hits. The way practitioners learn to step through, either forward or backward, is a desirable quality lacking in many FMA only trained fighters. It lays a good foundation for bilateralism. We seek to blend it into the triangles of Kali and Kali approaches to hitting. This is a brief description. Our material which blends the two I call "Los Triques" which simply is my effort at humorously saying "the three Ks": Kali and KK.
Hope this helps,
