I had the opportunity to see the Chibana version of Kusanku. In my past I learned or saw the Yara version, Shotokans Kanku version and Shimabuku's Yara version. I found the Chibana version quite interesting. I know that there are plenty of versions but how many named versions (where a specific person is included in the name of the kata -- such as Chibana Kusanku, Yara Kusanku) are credited to individuals. Just curious
