Right now I have a quark cr2 mini on my keychain. While the light is great, small, etc..., the fact that it doesn't support rechargeable cr2 (and the overall limited availability of rechargeable cr2) make my next upgrade confusing. More specifically, I want to get an Atom and the 360 kit but whether or not I get the CR2 or 123 is a big decision. To me, not having rechargeable batteries on your main EDC is crazy. If I use the light for 20 minutes, I am leaving the house unprepared and obviously bringing an extra battery doesn't always work. Sure using primaries in your car with a flashlight works, because you can keep extra batteries easily. I feel like getting the 123 is extra size I don't need, especially when using the headlamp but obviously there is a huge advantage in RCR123. I'm also not super inclined to buy new CR2 batteries (rechargeable) even if they are available and reliable, etc.
Any thoughts?
