Hiflier- I've always thought that a good strategy! Saves on bullets, saves on BF's!!
However, there is validity in the thought that once acknowledged there's gonna being a lot of groups out on the hunt for specimens/trophies. As far as specimens go, it's not going to end with just one, and with trophies, well...that's nearly limitless, and which ever comes first, if one does, it will open the door/floodgates for the rest.
That's simply how we hairless dwarves seem to operate....
