Hey Guys.
IMHO Kata should be practised for Kata's sake, and the "applications/bunkai" should be used mearly for a brief explanation to learn the Kata faster and better.
Actual application of the techniques as they are sequenced and done in Kata is by all means not street effective. But change the sequence around, Combine them differently and you can get to some deadly combo's.
But, Kata as is, is not for use in combat, You'll only get yourself hurt, Badly.
