I agree with the iceman here. Deadening material is deadening material. Compare to whats in your car now, its a huge improvement to use anything. The difference between brands is negligable - except where adhesive is concerned. Dynamat will pull your fingertips off, Ive never used Brown Bead, but if it sticks well(and of course you use a roller to install it) then it'll be fine. When you're doing a whole car, you can really save some dough over Dynamat, but start with one section and see how it does.
