Rage heads are good, not great and far from the answer to all your broadhead needs. If you were not happy with the durability of the Muzzys you will NOT be happy with the rage heads as far as durability goes. Not all shoulder shots are the same and 1/2" difference in shot placement can mean the difference between a full passthough and no penetration at all. I am not saying not to try the rage heads, just be aware that the Montecs and Muzzys are much tougher overall compared to the rage heads.
