It all depends on what your looking for. Do you want a perfect fit from the beginning with Jute, or can you deal with no sound deadning and having the carpet settle into place? Are you trying to get rid of some weight while your at it?
I Bought carpet from texas mustang for like a 100 buxs. I like it, not a perfect fit from the get go, but no Jute backing (much lighter) it eventually settled in.
