Re: Crosstraining Aikidoka: A Survey
Short answer, 'Yes'. Like I say, it's early days (more theory and enthusiasm than proven application), but the 'gaps' in aikido technique where an atemi could fit seem to lend themselves to the 5 basic hsing-i fists without compromising ones flow or posture.
You don't so much throw a punch, but move through your opponent with your whole body, fist first. So if your partner/opponent doesn't play ball and respect the ma-ai you're seeking to establish, he can have one of these instead. The 'root', so valued in Chinese internal arts, is more mobile than in tai chi (though, ultimately, perhaps less powerful) which makes it more aikido-friendly.
As with your arnis/silat experience, the arts are 'at opposite ends of the spectrum', which is nice. If you give it a try, let me know how you get on.
