They fly great, i have the 3 blades and shot 2 deer with them this year and they had huge entry holes and didn't make it far. Not as much blood as i would have liked to seen, and the blades will come out in your quiver easily, also both deer i shot i had the blades get bent on them without hitting any bone so the durability of the blades is very questionable. All in all if you hit the pump station, he ain't going to make it far but if you hit the shoulder bone im thinking it's not going to be you favorite head after you go looking. I still have mixed feelings about them but ive always been a fixed head person...
