I used the heads this year and for hunting they are a great head. Penatrated much better than my NAP Spitfires. The only thing with them is if you used them on a 3D target it will bend the furlow. The furlows are pretty weak and made of Aluminum. Me my dad and brother used them this year and took a total of 5 deer and the heads held up great only thing that happened was one lost one of the small blades on the tip. They will be on the end of my arrows next year that is for sure.
