If your puting out alot of KE, they are great. For my setup at 58 pounds, not so good. I shot a doe last year and made a perfect shot, The blood trail was non existent at first, until the arrow fell out of the hole. The broadhead stopped on the far side of the deer, just under the skin. The shot was a little high, but the downward angle was steep. With a fixed blade, i would have had a passthrough easily
