grouch, my CAD software calculates the polar inertia for me, so all I had to do was describe a "for instance." With a 4 X 2 "C" fully boxed (0.090 walls), the polar inertia is only about 10% greater than with the triangulation. So, if you have some need to triangulate a section, there's not a whole lotta difference. Note, however, that the fully boxed is the better choice. And, it's lighter.
