I definetly do not see it as getting BH' s to imitate FP' s. With the proper spine and tune your BH' s should not be plaining out of your bow. If they are not a FP should follow them until air drag begins to slow the BH arrow to a point that they hit lower. That distance for me is beyond 60 yards, up to that point at every distance BH' s and FP' s group together for me. My groups are tight to my max yardage of forty and I have no problem getting pass through' s on Moose, Caribou, Grizzly' s, Black Bears or deer, so I don' t see how this has hurt me in the least.
