x2 on the 2AA SF-E2L.
I just got the 2xCR123 E2L and its a killer little light. Dont let the Lume numbers/specs fool you. My version E2L is Spec'd at 60 Lumens, Bigchelis measured it at 110 Lumens in his sphere, and it was ruler flat-regulated and remain fixed at 110 throughout the test run.
Outdoors its a thrower (IMHO). Not a spot beam, but more like a ice cream sugar cone. Keeping up with my lights that measure in the ~130L range. I expect great performance out of the new 2AA version.
The Romisn RC-N3-Q5-II should be on your list too. Its a simple 2-mode, forward clicky.
I generally am not a 2AA fan, but that could change soon.
