Thanks for all of the suggestions. I got to playing around with different arrows and found something interesting. The supper carbons that I’ve been shooting for the last two years will not tune, but I fletched a brand new one out of the box and it tuned perfectly. Do carbon arrows lose some of there spine over time??
I don't know first hand, but I've heard they can. Of course it takes many many thousands of shots. While I was writing this I thought of something that is most highly overlooked. NOCKS. Try replacing the nocks and see what happens.
