Speaker isolation - spikes on puck, springs, sorbothane

I’ve recently become aware of the idea of using platforms like townshend, or Gaia, or a suitable Sorbothane product. My Wilson Sophia are 160lbs each and currently sit on a suspended second floor in my living room of my wood frame house. I’ve also discovered a plethora of isolating cable springs used in aviation and industrial applications. My speakers are on the wilson conical diodes and brass discs. 
there are number of ways to do this, the cable style seem they’d be the best at absorbing the widest frequencies vs a straight spring. 
 

any thoughts observations, cautions?

This is a pretty sticky topic. One likes to decouple, the other to ground the speaker.

In my case, I use Vandersteen's. Mr. V. believes that grounding the speaker to the floor is the best method.-See his newest speakers- they have a 3 inch granite base that keeps them from moving so that the speaker output is maximized (okay, I can't say exactly what he did, but that is the gist).

I also live in wood frame house, and adding the granite plinths made a significant difference for the better.
