I disagree with the guillotine. I shot it numerous times with numerous setups and can't get it as true as I would like it to. Especially at distances I know I can shoot good groups at. I also tried and hear stories about the rage. Yes, when it connects and works properly, the head is lethal, but I have heard stories and have also had some not open for me. I do not think their flight pattern is as true as others I've tested as well.
Since my trialing days, I've settled on one broadhead for turkeys that is consistent with my field tips time and time again and also stops a bird dead in his tracks. It also eliminates pass through, which I've watched birds simply fly away or hustle the heck out of dodge with other heads. I am talking about the "Turkey Tearror". This broadhead allows me to shoot three inch groups at forty yards as well as put the game on the ground where it stands. It's a good feeling when they just flop for a few seconds and expire instead of trying to track it down or use a dog to find your kill. Just my two cents, but I will tell you this I will never go back to those "other" heads after some experiences I've had with them and I have yet to be dissappointed in the field the last 3 years from it. Good luck.
