The APG has Quickdraw version of light steel and light wooden shields. My fighter uses a heavy steel shield, but I'll be picking up a mithral one when possible. Since mithral effectively lessens armor categories (heavy to medium and medium to light), what do you think about constructing a Quickdraw mithral "heavy" shield? It'd only be a pound and a half heavier than the light steel shield, so I think it makes sense. I'd still have to drop some feats to be able to draw it and my sword together, though...
