The arrows are most likely a little overspined and if fletching cures the problem and they group well then I would just shoot and forget the paper.A string loop will allow you to use a slightly lighter spined arrow and with no fletching that may be the only problem.

I know the ICS chart says they are correct but you would be amazed at how many charts play to the stiff side just for a little margin of error to the stiff side is better than to the light side.


I disagree that an arrow can't be tuned close.If the spine is dead on it will tune at 6' as well as 20',I have done it with the help of Archers Advantage.I will say that my 3d arrow will not and as long as they group,I could care less.

I have a friend that shoots the semi pro class and he shoots arrows that are so stiff that they will tear that bad or worse with fletching,he still finished in the top 10 in points last year in the ASA.
