Yes my friend Ken,I definitely have functional ideas visavis iaido,kendo,etc but my iaido,kenpo,tang soo do,and WAY OF SIMPLICITY sensei has positively forbidden me to share any of my ideas that are purely iaido.However,he's fine with me sharing some things that I do with the blade (sword or knife) stick etc. as long as I don't stick the label "iaido" on it...so I call the modifications that I use ATACX GYM FUNCTIONAL IAIDO. There are definite differences and imo marked improvements in my expression of iaido very much along the lines of my functional variants of Kenpo,Shaolin Kempo,Muay Thai,Taekwondo,Tang Soo Do,Capoeira,Judo,Hapkido,Wrestling,and the other arts and disciplines that I hold dan to Professor rank in.Hope that's helpful...izzat acceptable?
