Thanks Rick. I feel a bit sheepish. As you can tell, I'm a little late to the game. In past years, I have purchased PT Auroras as gifts for family members, but I'm just now contemplating my own first headlamp. After a bit of research, I narrowed my choice down to the PT Quad, EOS, and the Petzl Tikka XP. After reading the forum here and elsewhere, I think the Quad will suit me best (incidentally, REI has them on sale for $20). It will mostly be for general use (camping, hiking, hunting, some dark slot canyons, emergencies, etc.). Anyway, thanks Rick for the heads up and all for the great info on this forum.
