And it won't be my last. I love the art! And what's more, I'm training in a real dojo, not a McDojo like my TKD studio. Currently, I'm mixing my TKD training wtih aikido so I could become a more rounded out martial artist. I don't plan on advancing far in AKD, but then again, I said the same thing about TKD and now I'm about to go for my green belt soon and I'm going to double test to get my blue and brown belts.
i'm glad you like aikido that much. i myself went to few training sessions too. and as far as the double grading is concerned, your instructor allowed it?
