Isolation devices- to use 3 or 4 footers?

Anyone here use the brass cones from Live Vibe Audio? OCD Mikey raves about them. He's tried Townshend springs and finds the brass better. He hasn't tried Stacks yet. 

Innuos uses 3 footers. Maybe there is something to it.

I prefer having four feet on my gear that isn't rack mounted. But consider that it's the three-legged stool that never wobbles. It's why photographers use tripods.

More effective, or sounds better?
I find 3 sounds better on my Garrard 401 tables. 

I use 4 footers on my Preamp and 3 footers on my Amp because my manufacturer used 4 footers on my Preamp and 3 footers on my Amp.

That being said, I slightly off-set one of the footers to help mitigate any tiny standing-waves that the electronics transfer to the Aluminum casing (which, in-turn could be reflected back into the electronics). 

I use inexpensive footers, and they seem to work very well (converting motion into heat) - the improvements are obvious, not subtle.  My system is posted.  

My only advice may be to start with something inexpensive and see if you are satisfied before going high-end.  If the inexpensive footers are not satisfactory, expensive isolation footers will work very well (from all reports).
