I've been a 3 blade guy most of my bowhunting career and have been shooting the Instincts at a bunch of animals since they first came out. Turkeys, deer, antelope, bear, elk - they have been devastating on everything. I love the long cutting edge and low angle and really believe it makes a difference with penetration. I honestly think that the head has been the difference maker on the successful recovery of more than one marginally hit animal.
Excellent broadhead, and I am sitting in a turkey blind as I type this with 4 of them mounted on my arrows.
