I've thought about the extra flashlight idea. I have a Fenix LD15 and have not been able to find a smaller AA flashlight out there. The only problem is this method eliminates the guaranteed freshness of the battery. For example, someone might come around and play with that flashlight, unbeknownst to me. Or I will play around with the flashlight because, well, it's there. I suppose I could disable the flashlight, but then I might as well just use a case... decisions, decisions.
