low tech rubber tweaks

I read a post by Jejaudio in which he described a technique he uses with some success:
"I went to the hardware store. Strolling down the plumbing aisle there it was...A simple Sillcock Handle(round, out side faucet handle)
Combine this with 1\2 round chromium steel balls grade 25. That's 7 balls per handle 6 under the faucet handle, one on top. This one ball is the one that will be touching your unit. I use 3 faucet handles per device. That's 21 balls per units. The 1\2 balls fit in the slots on the faucet handle perfectly."

now don't laugh...but my question is...if rubber helps to eliminated the vibrations which would work better
1) hockey puck on bottom, vibrapod on top of that, superball on top of that?
2) Jejaudio's idea substituted with superballs?

I plan on getting a bunch of superballs, hockepucks and faucets thingers and trying this all out for myself for the fun of it:)
just wondering if you had any predictions!
