I think there's a point where optimization goes too far.  I have some
experience with the manufacture of hollow airfoils, and this sounds
like an incredibly finicky operation with the potential for all sorts
of defects.  Remember, it's not the smallest defect you can detect,
but the largest one you might miss...
