I actually came from a DKI's student. I learned NaiHanChi Shodan was first and then 5 pinan/heians. I also learned Neisheshi,Bassai, Empi, and Hangestu. naihani nida and sandan came after reaching shodan. Styles do differ drastically in method and teaching. In G. Dillman book's, he calls his method, "Dillman Method." Raul, where do u train, at Kyoshi Gerri's school in Farmingville-curious?
