I wonder which form would be better?

I have not tried any of these and am just reading along but from the http://sounddeadenershowdown.com/ site posted above, they seem to have done their homework on the materials. A note about the closed cell foam from that link (again I'm only comparing info in this thread and have no experience in this):

Closed Cell Foam Does Not Absorb or Block Sound
I know people say it does, but it doesn't. It's too light to block anything meaningful. It doesn't absorb sound well for the same reason it doesn't absorb moisture. Combine that with the thickness consideration in the next section and it just doesn't. CCF is a mechanical not an acoustical material. It's a gasket.

I read through the site, very interesting read. I will have to do something with the Teener, Mercedes and Tracker so this thread is very timely! (IMG:style_emoticons/default/beer.gif)
