I'm kind of liking the UI, it's like the Quark Tactical, except instead of programming the UI like you do with the Quarks, the Fenix has preset modes, which depending on if you feel that the Fenix 3 different presets are to your liking, might be a simpler UI to a simple but advanced 2 moder compared to the same head twists and then choosing the levels and waiting 10 seconds like you do with the Quarks. When I first saw the Tac Quark's UI I thought of a bunch of different combinations and the TK12's different modes were kind of similar to what I'd choose for each given situation, except Fenix's hunting would be more of a roadside emergency mode and camping would be 50 and 5 lumens, but I agree with the outdoor mode.
Those beamshots look like they have a nice clean beam, too bad they don't come in warm tints though. I wonder if perhaps the Tac Quarks may have given Fenix the inspiration for this light?
