If all arrows were the EXACT same, they would (should) all hit the same hole.

But we all know that arrows have manufacturing tolerances for spine and straightness. These tolerances start to show up from arrow-to-arrow using the HS. You can go through a dozen arrows and see the difference in impact points (if any) on the target. It's easy to weed out problematic arrows, and makes for much more consistent broadhead flight as well.

BUT, the HS will shoot any GIVEN arrow into the same hole time after time, no matter how out of tune the bow, or even if the arrow is bent.
