For that price, the RAAMmat is a lot better deal! That stuff wouldn't be near as good either. If you don't want to deaden a whole lot, you can always order a half roll from Rick too. Though a roll of RAAMmat (62sq ft) is only like $100 + actual shipping with the forum discount. With that in account, half a roll then would only be like $55-$60 for 31sq ft.
