Subwoofer Footing - Connect or Isolate?


What is considered the best way to "foot" a subwoofer, should one try to connect it with the floor or isolate it? I have a REL 7i that I have firmly coupled to my wood floor with the weight of a 42 lb curling stone, mainly because it looks cool. Would some sort of isolation be better and reduce resonance from the floor, or could the connection with the floor help "drain" resonance from the subwoofer cabinet?

SVS sells their SoundPath sub isolation footers for only $50 and offers a generous risk-free trial so you can try’em at home. They are said to both improve bass and reduce transmission and get excellent reviews from customers who bought them. No brainer in my book. Best of luck.
Another Auralex Subdude user here.  Cleans up muddy bass that obscures midrange detail when flooring is problematic.  Everything is more refined and detailed top to bottom.   
Great feedback everyone, thank you. As a low cost test I ordered some Nobsound springs, though something like a Subdude is definitely under consideration. I shall report back.
Has anyone tried the  Auray ISO-SUB Subwoofer Isolation Stabilizer?  Same overall dimensions as the Auralex but made of slightly different materials.
