Torsional stiffness, example Klein

Jimbo said of Klein that "they not only figured out the torsional
stiffness thing, but actually acted on it. they deserve medals for
that."

Can you give us some references, preferably with pics, and maybe you
want to spin out a short par so we know to look for precisely what
you're referring to.

Fangs,
