RE: Mechanicals heads?
I have used the Rage for the last 2 years. I have had zero problems with them. I have killed 2 bucks, 6 does, one exotic, and several hogs in that time. My basic observation has been that as long as you are smarted then the broadhead then they work fine. (i.e. after you take them out of your quiver, make sure the blades are properly seated and you will not have problems).
