Well Said SBN,
I look at it the same way...When I first stepped into a ryukyu kempo dojo the first form I learned was the Ryukyu Naihanchi Shodan no Kata...in Tang Soo Do we have this as a chodan form, but the Ryukyu Kempo students learn this form first, the stepping is easy to pick up, but does not provide knowledge to transition into the enbusen of say the Pinan Shodan, where you must pivot, shift weight, use several different stances etc. As such some students have a hard time moving into the "moving forms" i.e. Pinan, Seisan, Passai, Kusanku, Nieseishi...In Tang Soo Do I belive that the Kicho hyung serve a great purpose, they are very basic in design but provide a solid "FOUNDATION" [Kicho ;-)] For further learning.
This is the Um/Yang concept everything has a higher and lower level, the above is the lower level of understanding in Kicho. In my experience everything conforms to Um yang as a natural law so if we examine the higher side of the kicho, bunsok is there, we just need to look ;-) I think it was Funakoshi Gichin that said "The Taikyoku (kicho) are both the most basic and the most advanced forms in Karate Do".
As we try to understand our art we must realise the we will never attain actualization of mastery in any aspect, there is always more to learn, even from the very first movements of Kicho Hyung Il Bu, they just become more apparent as we train and train...
Take Care,
