I do not really agree with the view "a certain feeling with a certain kamae". It narrows down your own possibilities.
I think it is important to adapt the situation, the necessity and the kamae to each other.
A kamae that might have an "agressive" feeling somewhere, should as well be able to be used for a full defense and vice versa... and for everything in between.
After all, it is these things where kyojitsu comes into play, desu ne?

In other words: forget about the related feeling and play with it. Try jōdan no kamae for example with a sense of aggression, try it with a sense of neutrality, try it with a sense of caution, try it with a cautious aggression, try ist with a neutral caution, try it with a neutral aggression. You will find out that it might be difficult now and then, but you can break the obstacle.
I for my part can project a feeling of caution on kamae like bōbi no kamae and not feel uncomfortable with it.
"Moving kamae" is an oftenly quoted sentence in the Booj, but it does NOT stop in your taihenjutsu, it also should also be moving in, with and by your mind.

Just my two cents... but I'm sure there will be quite some people disagreeing on my views, for that's what they are: just my views...
