I probally do suffer from some mild brain damage brought on by my head getting baked in my Hard Hat in the hot sun from my job working construction in the summer, but it not baked enough to where I would use nylons in the main spar. I was trying to get across that this would be the only way for the wings to shear from the Plane during a crash, but they would surely shear and cause the crash to begin with. After I posted my first comments, I read it, and it read like I was recommending nylons instead of the steels. So I figured I better hurry and correct myself even though most people would know better than to try this anyway!
