A little update... I received the clicky and Preon 1 body and liked it, though the color mismatch was rather ridiculous with the red preon parts and grey A3. I went ahead and ordered a "full package" including a head, preon 2 body, and pocket clip. Not sure if I am going to do the 1x AAA or 2x AAA route yet, but 2x AAA might not be much of a hassle to carry since it's so thin. I also ordered Norland 61 adhesive and a tritium vial to add a locator to it. Turned out to be an expensive (to me) light, but worth it I hope
