Not sure on the AA front but I have a AAA Fenix L0D Q4 and love it. The slightly updated version is the LD01. I've heard good things about the AA equivalent the L1D Q5. Aren't the naming systems great.
I am going with the Fenix LD01. It seems like a great all rounder and perfect size. 50AUD shipped. Perfect. Thanks for the suggestions.
Not sure. It just says keychain included in the package contents description. Why do you ask?
