Once you have a broadhead that works good for you and you have confidence in, it make good economic sense to stay with it. It doesn' t have to be proven superior, just effective. So far, everything I' ve shot with Muzzys, has been quickly recovered. My experience with them, tells me they' re good enough for my kind of hunting. With Muzzys I have lots of practice blades and regular blades, so I never run out of them and it' s cheaper to buy replacement blades then it is to buy new broadheads to try out.
