I am not knocking them. But like others have said, I am not laying out $85 for 3 heads knowing that I am going to blow through watever I shoot and ruin the broadhead when it hits the rocks on the other side. Where I hunt in the hills whether you hit or miss you ruin the head becauseit's so rocky. With the KE that I am shooting (78 lbs) I have been getting passthroughs with mechanicals for years on everything from 100 lb does to 300 lb midwest bucks. When I hunt in the river bottoms that wouldn't be an issue but then I would have to switch heads to hunt from one terrain to the other. I just don't see the point in fixing something that isn't broke. Now, if I were picking a headfor my wife whom was only going to shoot at a deer or 2 a year and KE and shot placement were potential issues then I can see making the investment. Because I am sure they are truely awesome heads. But for me I will stick with my mechanicals.
