I'm a Canadian - we don't have fair self-defense laws in this country; it's almost as if the law wants one to let one's self get pummeled in an attack, and then "trust" that the law will deal with the offender.
This makes perfect sense, as to why you would lean towards Soresu's more defensive (but not passive) approach to combat. We do what we know, I suppose. lol
Though that does really suck...
I like feinting attacks, grappling the other deulist's hilt, and swinging at their feet.
Honestly, that sounds (at least conceptually) like a very aggressive Shien, to me. "Sith Shien," perhaps? : p
Though there's nothing wrong with running when your in a losing situation. lol
As for me, conceptually I prefer Djem-So. The measured relentless assault and finishing the fight quickly on my terms appeals to me.
In practice, I'm probably some screwy combination of all 7, plus whatever random bits and pieces I've picked up from past experiences.
Honestly, that way I see it, we all lean to one philosophy of and set of techniques, but incorporate the parts of other forms that appeal to us.
Like I said, I prefer an Ataru-Shien mix, but I also incorporate the occasional Shii-Cho swing, or Makashi thrust, if the situation calls for just such a move. : )
As everyone knows... I'm a Makashi guy

That's because of your background in Fencing, correct?
In a perfect world Heavy on defense but when the opening presents it self to end it quickily and decisively. that opportunity is taken without hesitation or remorse.
That actually sounds like Soresu to me, with the emphasis being placed less on defending until your opponent is tired, and more on patience and waiting for the right opening to end the fight quickly and decisively.
Shii-Cho as always spoken to me for some reason, I like to keep it simple. Then again I appreciate all the 7 forms for different reasons.. Maybe I'm a Niman guy..
Shii-Cho is an excellent form, all on it's own, and isn't appreciated by enough people if you ask me. : )
I also appreciate all seven forms' philosophies, and the applications of the ones I feel I understand well enough, and I will occasionally use all of them. What makes me an Ataru user, I feel, is the fact that it's techniques and philosophy are what drive my dueling. I simply sprinkle a bit of everything else on top of it.
I hope that makes sense. : )
