You just need to get your head around it.From the POV of the vertical axis, the mass of the fishing weights is just one more component in the total effective mass of the structure that is attempting to rotate around it. Whether that mass is at the headshell, at the c/w or elsewhere, its all part of a single, rotating structure. Adding more mass or moving a mass farther from the axis increases the effective weight of the entire structure. It's just a matter of degree.
The other day you argued that a small headshell weight would only alter resonance frequency 1 Hz or so, so it wouldn't effect sonics much. I had to explain that the greater INERTIA from raising effective mass allows greater cantilever deflection, and therefore greater signal output, before RESONANCE even begins.
Now you quote an identical experience back to me. Yet you still don't see that raising effective mass by another means would have a similar effect?
I despair...
