Hmmm...
I have shot nothing but expandables my entire bow hunting life. I have had nothing but tremendous success from one animal to the next-big or small. I do not shoot Rage heads because I found they open during flight with my set-ups (not good). Fix blades plane too much, and thus, I hate them for not giving me the accuracy on which I depend (yes, I know how to tune a bow). Tom, like you, I experiment with one head after another. I will not tell a soul which head I use because what gives me confidence may not give you confidence. I would rather you acquire your own confidence...test for yourself and avoid the generalizations you constantly hear. That's what we do when we want to become proficient bowhunters!
One thing us bow hunters never factor: does the animal want to die? In nearly every cases, the answer is no! They spend their entire lives trying to survive. Do you think a hole in/through them is going to change that? I have seen animals shot with both fixed blades and expandables. The shots were picture perfect! Two weeks later, the animal is still up and walking-as much alive as the day they were shot! The wound is actually in the healing process. Bottomline, they do not always die when we want them to die! Do your best! Practice, practice, and practice-professionally (every day, not every once in awhile). Improve your tracking skills whenever possible (I track even when I see an animal die within sight-for practice)! We all could learn a thing or two from the Black trackers-they are nothing short of magical! When in their presence, be nothing but eyes and ears! Do not be afraid to ask questions! You'll build a enduring relationship with very little effort, and the skills you learn might be the difference between a cat in the bag or nothing.
Tom, I couldn't get your link to open.
