Choosing kata for black belt

[bushido_man96]

the concept of picking a kata for a bb test is strange to me. in my school we were required to perform every kata we knew for that part of the test. how does BB testing work in other schools?

This has been my experience as well. Also, I notice that many Karate practitioners talk of choosing a kata to do at a tournament. At the tournaments that I compete at, we usually have to do the form for the rank we are, or the one below, if we have not had the chance to learn the new one yet.

Differences in styles, I guess. It makes the world go round.
