I stand by what I said... It is a good broadhead, narrow being the same width as a Woodsman or Razorcap and a few others. Which are heads I use for tougher critters, big hogs and the like, where penetration can easily be compromised. The angle of the blade is a bit steep, for lighter bows this could be a problem especially if bone is contacted, not much of a problem for what I usually shoot...
I haven't had one break and they hit some pretty serious stuff... Not sharp out of the package, but I got them popping hair easily with the same technique I use with my Snuffers and Woodsmans.
All that being said, I don't own a G5. I gave them a try as I was intriuged by the design. They worked for me, but for the size, I have several others I like better especially for the price.
