After deciding the size now the decision on foam or dividers? I am going to store 2 Einsteins and 2 batteries. If I go with the foam I can store the items but if I go with padded dividers I can store more stuff like cables, speedlites etc. This will be checked baggage which one you would recommend? I gues I can make the dividers really snug but will it reach the quality of foam as far as protection?
