I am following what your saying there guy. But you don't seem to be understanding what I'm saying. All the research in the world is not going to trump my personal experiences. And I have a broadhead that I like, with outstanding penetration qualities IMO! Especially for my set up and what I hunt. I shot fixed blades for about 5 years. I was pleased, but I was not content. I started to experiment with different heads. Had reasonable success with most, some not so much. I used the rage two blade and was impressed and will stick with it until I feel it fails me. Carrying a spare tire is not the samething as expecting to make a bad shot. Some things we have control over some things we don't. I believe I have control over where my arrow goes. If I didn't I should stay at the house. But yes i do know that stuff happens, and that stuff has happened to me while shooting a rage head. The deer moved, and i reamed the shoulder, guess what? The shoulder shattered and the arrow passed through and burried in the dirt. im not tiffany lakosky, i shoot my bow at 74lbs with a 30" draw length, lack of penetration has always been a non factor. However accuracy is a factor with my set up. So I stick with the rage two blade
