hello everyone,

Once again I am calling on the collective knowledge, experience and wisdom of the folks here at ETS. It's time to upgrade my headlamp and flashlight for scouting activities this year. I was also thinking of standardizing battery size, so I am looking at a smith and wesson MP7 series flashlight in AAA and a black diamond storm headlamp in AAA. Anyone with experience with either of these lights care to comment on quality? Also, other than the convenience of only having to bring one type/size of spare batteries, is there any other reason to consider standardizing battery size? I have never really given that idea much thought as I always seemed to have gadgets around the house that took lots of different size batteries, so i always seem to have ready supplies of AA, AAA, 9 volt, C and D batteries hanging around. Comments and insights are appreciated and welcomed. As always, thanks in advance for your words of wisdom.
