Got to admit I don't really understand the fad for elaborate weights that have the main effect of running up costs. (Not picking on this case specifically; it's something that's been going around.) It seems like the cutout for the weight might even reduce the stiffness of the frame, if it has any effect at all. If I really wanted it to feel and sound super solid, I'd try a wedge-shaped base of pure, solid aluminum and then drop a sheet of sorbothane in the bottom.
But my thoughts are always on functionality; that's just how I am. I don't "get" artisans either.
Also, the plate as shown does not have cutouts for Banana Split or DZ60 split spacebar. Would be nice if it did.
