Just to throw a different option out there, if the case is for major airline travel only I would recommend the Aurora Proline. It has a detachable backpack on it, 2 large cargo pockets, arrow tube pocket, holds 2x bows, wheels on it, backpack straps, and is airline approved with their airline approved locks,with ais 45x16x6.5" inside, Plus it's cheaper than a double SKB.

If/when I get to the level where I am competing and traveling on a national level and need to travel this is the case I will be using.
