Have any of you made up your own kata for competition? How did you get started? Is it better to play entirely to your strengths, or does a creative kata need to be more well-rounded? Is it better to use the whole ring? Should you always start in the middle? ....I could go on and on, as I'm trying to start this, and I'm totally flummoxed. Any advice, information, experiences, etc. will be greatly appreciated.
