Enjoyed the falling pun. But yes, two totally different things, but the whole rooting portion and the twisting is what separates it, and why it threw people off when I did it during fencing. Seeing a fleche would be totally normal.Yes, they are completely different things in purpose and execution. You and others brought up leg crossing in relation to fencing and the "fleche" seemed to be the topic. I meant no similarity other than this. Maybe I executed a fleche, "falling" into a wrong assumption as to your reference. Kosa dachi is, as you said, a rooted stance while the fleche is more of a radical movement. I think we're on the same page, just started out of synch to start.
