HI, I'm ready to start framing out the inside of my 8' concrete basement walls. Is ther any reason why I should use 2x4 instead odf 2x3? Would either be easier to work with etc?? I do not need the added strenght of the 2x4's since my walls are 8-foot concrete. Just making a space for wires and added insulation. I will be finishing with batt insulation, vapor barrier and drywall. I will be adding this to the 1.5" styrofoam already on the concrete. Thanks!
