Yes your a littl eover-spined but I would rather be over-spined than under. Out of the 400-500 Mathews Ive tuned in the past there is one little trick that seems to work when nothing else does.

Instead of centering the arrow in the berger button hole (arrow rest hole on riser) put the arrow through the bottom half of the hole.

Dont place a whole lot of faith in paper.

FYI - I shoot a 31" 2315 w/ 125 Thunder Heads @ 71 lbs out of a Mathews Feathermax.
