is loaded to within its design pressure range. It is made to convert vibrational energy into heat, but will only do so if the weight on it is within its specified range. If you overload it, it won't dissipate vibration. See the Herbie's site for the weight ranges intended for the various footers.

I'm not sure what you mean by "blue circle puc." AFAIK, the Blue Circle Audio Puck is a specialized capacitor used in their power supply upgrades, and not a damping device.

What I would do is order a sheet of Deflex rubber and cut pieces to fit under the weights you intend to use. I would look for weights made of material that does not ring with a definable tone when tapped. Iron weights would definitely ring and create more trouble for damping. However, steel shot in wooden boxes would be less lively and give you magnetic behavior similar to the solid iron. Mix the steel shot with quartz sand for even less acoustic vibration.
