Corey006. The grouping to the left of the broadheads show a stiff spine reaction for a right handed shooter. So how do you weaken the spine without changing the arrow? Use a heavier broadhead and that will weaken the spine a bit. Another trick raise the poundage of the bow some. Decrease spring tension in the rest if it applies to your rest. And also move rest in 1/32 inch increments to the right, towards the bow. These are the things to try to correct a stiff spine reaction. Good luck...
