Awww c'mon Charlie, where's the fun if we can't obsess over something
I did at one time obsess over which head would kill better etc. When I first switched back to trad 7 or so years ago, I thought I had to shoot a STOS or similar 2 blade for penetration because I was handicapping myself with trad equipment. Over these years, and after a few practical experiences of my own, my views have begun to evolve slightly. I've found with the setups I typically shoot, the logical choice among quality broadheads is much wider than I had first expected.
I'm on a quest to kill all my critters this year each with a different broadhead. Mainly, because I think there are probably 25-50 good heads out there that will all perform within a few, imperceptable percentage points of each other for anything on this side of the pond and most anything else below the size of zebra on the other side. Dr. Ashby's reports have been very enlightening to us all...but for most game on this side of the hemisphere, you could grab most any sharp cut on contact head and hunt with confidence.
