If i could give this zero stars, I would. I was convinced I should make the switch since I tend to hug the shoulder a little tight. I have shot the same compound for 14 years(Matthews HeliM), and this is the first time I have completely missed the block. I thought maybe it had to do with the twist. NOPE! I shot them from my recurve Bear that I have shot for a few years now, and completely missed the block. They wobble all over the place and never keep the same line. I dont know how they work for anyone on any setup. I have used different bows with left and right twist with several arrow weights and it is always the same story. Inconsistent and unreliable. I would never shoot these at an animal. I will 100% stick to my Swacker broadheads. I love watching the THP guys. I've learned a lot. I've enjoyed a ton of videos. This is one product I cannot get behind.
