One quick item. i didn't know the M6 could swap between the LED and incan till a week ago. i had been looking at the light now i am definately going to get one, and a incan module. also i learned the LED has a clicky, i hate twist for constant.the M6 incan was momentary & twist for "on". but that could have changed since quickview's review. so that too is a plus.
