Hello all. I have a couple of questions on using the TP-24 stands. We recently relocated and our new house has vinyl flooring on top of concrete slab.

First, is it better to use spikes with the discs they sit on, or use some type of rubber foot on the bottom of the stand?

Also, if I fill the stands, is the goal to make them heavier, or to deaden them, or both? I would like to use a light material like cotton balls or packing peanuts if the goal is just to fill them with something as they are already pretty heavy with the speakers on them.

Thanks in advance.
