The real question here is "do the clothes REALLY make the man?".
This Koryu issue is going down a different rabbit hole.
I think Tgace is right, these are two different but both valid quesitons/issues. Chris is right that preserving the intergirty of an art may be more important than the current practitioners. But it is also very true that when you are talking about the performance/execution of an art or style (either in kata demonstrations, kumite or a real SD situation) it comes down to the student and it is the student's natural talent, mind set, ability and/or desire that is important.
It would be interesting who you think would prevail in a fight between:
- an el' crapo, half-hearted student "training" in (turning up to) the most effective, rounded art there is (an art like mine) ;and
- a highly committed, driven, athletic student of a very one dimensional art whose techniques are even a bit subpar (ie the techniques themselves are founded on poor alignment and biomechanics).
