1) Fenix TK11 with white wand attachment - Keep it in my site toolbox two of 4 weeks per month.
2) Bitz Pocket Titanium - Most popular EDC for the last 12 months. It's plenty bright, tiny, easy to use, has a trit locator and is very durable.
3) Surefire C2 Centurion with an M60 - Alternate this with my TK11 so it's carried the other two of 4 weeks per month.
Here's how I settled on these out of over 20 lights; The TK11 was my main user light after it got dropped and dinged up a couple of times, and as I've mentioned many times before, is made of some pretty tough stuff and has taken everything I and others have thrown at it in some pretty harsh environments and keeps on going. I started alternating it with the Malkoff C2 after I bought the C2 to get it some carry time, because it's a brilliant light that I didn't want to turn into a shelf queen. The Bitz came out on top of all my small single cell lights on durability and as one that I didn't care about scratching in my pocket because it's bare metal and polishes up pretty easily. I alternate it with a Nitecore Extreme but after all this time I still prefer the Bitz for EDC because it's so much smaller than the NEX and is barely noticeable clipped to my pocket. Yes, the NEX is a lot brighter, but the Bitz wins on size and sits deeper in the pocket because of the clip than the Nitecore.
