My son has shot Muzzy 3-blades ever since he started hunting six years ago. I guess mainly because that's what I picked out for him. He wanted to try Bloodrunners, so instead of going out and spending his money, he borrowed one from a buddy. He took a nice doe. Broadhead came out the other side, but it wasn't a complete passthrough. He hit her right behind the shoulder from about 10 yds. He wasn't happy with the penitration he got from the Bloodrunner and is sticking with Muzzys. Before switching, see if you have a friend who is willing to loan a BH to test out.
