I used Slick Trick broad heads and they penetrated my green bag target about half way and did the same with deer. I couldn't get a pass through on deer so doctorbrady recommended two fixed blades, and I have been getting pass throughs and busting bones. As a tracker I recommend two fixed blades for when things go wrong!
Rage is great when things go right, but couldn't be worse when things go wrong! The ribs on a big buck bust Rage. I had one track where the rib on a buck broke off one blade on a Rage. Here the ribs broke off part of both blades!
