I am trying to figure out what the big advantage of this type of case would be considering that if the case I showed doesn't do the trick you would be adding 20-30+ lbs to the weight of your keyboard with a hard shell type case confused

Also, it comes to mind that if your using a Bk7m and other accessories piled into a case of this type the advantage of having a small lightweight module now turns into a case with stuff in that weighs as much or more than an arranger keyboard and case.
