I ordered mine before there was such thing as economy vs premium, but I think I have what would now be the premium version. There are a lot of threads on Hotheads....but the best way I would put it would be, very expensive, and very high quality. If/when you get them, you will say...."I could have made something for a lot less money"...but you will see how well they are made and think "OK". IMO they do improve the acoustics, and keep heat in a bit better, plus they look a lot better. If I did not have saddle leather interior, I would have probably gone with the thicker Boom-mats....but I'm still happy with my Hotheads.
