I think I'm going to put the FW3A here.

I just can't manage to clip it into a pocket without turning it on at least 20% of the time. I swapped the button for a rubber one, and I wasn't turning it on accidentally anymore but it became instantly ugly.

Maybe I'll have to stack some washers on the end of it to sitck out past the switch... I probably am going to add a washer to my D4's switch anyway.

EDIT: It's worth coming back to this to edit it. The o-ring mod that's become well-known for the FW3A has made it quite a lovely little light for me. The way it should've shipped, IMO.
