I have hunted with muzzy 100 grain and slick trick 100 grain. Both of them flew true to field points when my bow went through the tuning phase. Almost any broadhead out put in the right place will kill what you are aiming at. But this year when I shot a bull with the slick trick I was very impressed with how tough these are. The muzzy blades broke on me with last years elk. I found the broad head and it is going back into the quiver again this year. Very sharp and strong. I am sold on them.
