"neckdives like Stuka over Poland"
That dead spot elimination thing always struck me as vodoo acoustics. Any scientific defenders?
I don't have science, but I used to have a Fender with a really bad dead spot, and I put one of the Fat Finger devices on it and it made a huge difference.
That said, my back can't take neck heavy basses any more, so I want a smaller, lighter headstock whenever possible. I've even gone to using a weighted strap on my '76 bird because of the neck dive, so weights on the headstock are out.
