Loading speaker stands with?

Rehashing a common question, with a uncommon choice: I will be getting stand mounted speakers soon for a new listening room in my next house. I have always had floor standing speakers, but this room is small so smaller monitors just make sense. Obviously I will have them on stands. The question is do people load their speaker stands with dry sand or shot (or similar heavy dense materials) to stop resonance or to create weight for stability? I know the answer may be for both, but has anyone tried using foam packing peanuts jammed into the legs of the stand, and what were the results? I would guess it would soften any resonance from the metal legs, without creating a heavy, immovable tsand. Thanks for any feedback.
