Don't know if this has been done, but here it goes;
What's your favorite kata?
Mine are Yantsu and Gekisai dai kata as taught by Oyama. I know it sounds weird for a goju-practitioner to do those two but like I said; I'm not restricting myself.
But one that will forever haunt me will be.... Sanchin. What is so special about it?? Don't know, but I'll find out even if it takes me another 40 years.
