You might find this interesting. Mario McKenna demonstrates the difference of kicks from old style Naha-te, both in thr Toon-Ryu tradition and the Goju tradition. http://www.kowakan.com/sesan/#more-7848
You might notice the similarity of the Toon tradition to the Isshintyu front kick in SunNuSu (Sunse).
Gives one pause to reflect.
A big thank you goes to Mario McKenna for saving this.
