Re: Ikkyo vs elbow or bicep/shoulder
I don't want to launch into all the details, but I was wondering if you'd noticed something that is key for me? If you're into this, then the other details are, I think, all there too.
For me it is essential to grasp uke's wrist when the other details have caused uke to give me the inside (pulse area) of his wrist flat-on. I take that area in my palm and my thumb wraps around to the top/back of uke's wrist.
If I don't do this, my "spiral" ikkyo falls apart. It is so important to me that I think of it as equal to uke giving me his back when grappling.
