Molly, Like JDK said, its not the actual weight of the wood removed. Removing wood just below the barrel centerline enhances the perception of lightness, flow, and the blissful marriage of wood and metal, as does having the stock line just above the centerline of the ram rod, or even more. It gives it a life all its own, unique, and not something mass produced by formula. It helps if you have two similar guns that you like suddenly shown side by side. You will like one better than the other, its only natural, ask yourself why. You may indeed prefer the heavier look, nothing wrong with that either. Best to you.
