Well so far I've narrowed it down to 3 manufacturers, and 3 different products:
Tontine Acoustisorb3:
Tontine AcoustiSorb (pg6)
Insulco Semi-Rigid (John Sayers seems to like this one):

And also the Bradford Fibertex350 which has been mentioned in some other threads here on the front page:

None of it seems to perform quite as well. The Fibertex is extremely expensive, I'm concerned that the Insulco Semi-Rigid isn't rigid enough to stand without chicken wire (big problem for us as we want to make many panels quickly) and the Acoustisorb is polyester-based, which I haven't read much about in regards to effectiveness. From what I gather most people still prefer fiberglass for pure performance?
Thank you for the reply.
