The problem with superballs as isolation is that they are effectively elastomer "springs". They absorb that energy quickly, but they very efficiently put it back into the system! It's a rubber pogo stick effect, which is what always made superballs so entertaining to kids (and big kids). It's NOT what you want.
What you want is a substance that absorbs that energy and dissipates it rapidly, rather than putting it back into the system. In other words ZERO bounce back if possible.
I used Norsorex (dead, sad balls)to very good effect where isolation was wanted. Herbie's balls, footers, etc. also do a highly effective job. I didn't like Sorbothane, but this is individual taste.
The best advice will always be, as you said, that it's idiosyncratic to the system/situation. So experimenting with combinations of coupling and isolation is in order. And besides, that's half the fun of this hobby.

Making amends, or trying to, for numerous posts in support of the use of Norwsorex (dead balls) for resonance damping, I recently discovered that they don't work like i thought they did.
I'd love to hear a reason WHY they don't work, because intuitively it sounds (to me at least) like a good idea. And I had the things under several components, with brass cones, maple platforms and cork/rubber thingies under the main components. Then not long ago I lost one of the Norsorex balls behind the system when moving a component, couldn't find it, and had to do without it. I removed the other two balls and -- what's this new clarity and openness? So I then removed all the others I'd been using and the system sounded better than it had before. Replacing them with brass cones further improved the sonics.
Anyway, I hope that anyone reading one of my old posts praising the Norsorex reads this one too :-)
Can't find any of the old Norwsorex posts - tried searching for "Norwsorex"
I'm curious what you tried. Perhaps the reason they did not work was because you were putting compliance where hard coupling was required; if things improved when you replaced the balls with brass cones then that sounds a reasonable theory..now if you could replace the cones with something better..

Well I copied and pasted from your post (first sentence) But I see that you don't suffer from consistency, and you spell it differently so I'll try the other spelling.
