This will be my 3rd season shooting the Slick Trick 125's. They are the best head I have ever used. I have harvested 12 animals with them in the past 2 seasons, and the tracking has been very short. All pass throughs, and the accuracy is simply unbelievable for a 4 blade head. I use 3, 4inch AAE fletching, and they shoot right with my fieldpoints. You wont be disappointed in this head thats for sure.
