Do you think you can have to much arrow spine?
Yes you can. The best case scenerio if finding the correct spine that will tune with your bow shooting directly through the centershot of the bow. Remember that you can effect the correct spine of an arrow in tuning by adjusting the length of the arrow, changing tip and fletching weight, and adjusting the poundage of the bow to name a few.
