That would be what I am really looking for. The problem with most 2AA lights is they are too long for EDC. At least 5.5" usually. A 2AA spy would be only 3/4" longer than the current spy, and thinner as well. That would make it more pocketable than the ever popular PD and HDS. A 4 pack of eneloops and decent charger would supply all the power you need.
Too bad data would need to develop a whole new boost driver.
