Maybe you are right but these are marketed as having excellent acoustic performance, it's a plus that they are lighter to handle but more importantly they are also bigger in size making pretty much ideal size shelves for 2 miners. With the bigger size they will also be more stable if I just stack them up without mortar so that I can take it down it easily if it does not work out and re-use or sell them.
