I've trained in Fukyugata 1-2; Pinan 1-5; Naihanchi 1-3; Ananku; Matsumura Seisan; Matsumura Passai Sho & Dai; Wanshu; Seishin Sho.

My favs to study in depth are Nahanchi 1-3; Wanshu; Passai and Seisan.

I'm especially interested in training in Matsumura Seisan right now. The kata used to really frustrate me, but now I find it fascinating.
I spanked you as a baby, and I'll spank you now.
