Just wanted to share my experience with the Rage extreme head. Have used 3 blade rage without any problems and very good success the last couple years just wanted to try something different. Shot this doe at 29 yards quartering away from about 15 feet up. The head completely passed through and stuck a ways into the ground. The deer made it 20 yards max and fell down. The blood trail from the arrow to the deer was the sickest one I have ever seen. I have had some solid trails before with the 3blade version, but this was literally "the red carpet". The head was pretty well bent up but performed great non the less. Did not have any issues with new shockcollar delaying deployment as the entrance hole(as pictured) was massive. Exit hole was also quite large. For another year I will once again scratch my head at the people who bash these broadheads. Although I hate to admit it, I have hit deer in all kinds of locations, in all sorts of conditions and still have yet to experience the "failures" or "penetration issues" I see floating around on this site from time to time. Head was shot at 68#s from a 29' Strother Rush on a 5575 GT XT hunter.
