I hope they do what you expect of them. Sometimes a broad head flys great and cuts great as long as the angle of impact isn't too great. If that angle is too much then they do tend to "glance off" the intended point of contact leading to a miss or an undesired hit. I switched from a broad head that I was 100% happy with for that very reason. It would behoove a shooter to shoot those broad heads at sharp angles in practice prior to hunting to observe what they did.
