I seem to be in the minority here. I like how the heads fly, but performance on game is insufficient. Lost an Elk this last year using them, and am going to throw them away. Made a perfect textbook shot (on video), virtually no blood at all, arrow passed through, and was found. Looked for 4 days, still no elk. Very disappointed with this broadhead. In my opinion, not very sharp out of the package. Needs some improvement. Might be fine on deer sized game, but in my experience is lacking on larger game. Part of the reason I had tried them, was that everyone was bragging about these huge wound channels and blood trails. Definitely not the case this time. And for those of you who are saying that this is hunter error, out of 20 years of bowhunting, and 17 elk later......this is the first one that I have ever lost.
