For hunting situations, I don' t worry as much about the " stiff" side of an arrow. This will show itself in the tuning process and will be eliminated/pushed to the practice mode.
ALL the ICS type carbons I' ve had on my spine tester have a stiff side. It makes sense to me to have that stiff side aligned the same on each arrow. Tuning the arrow begins when you build it, not so?
I accept the ' not so straight' arrows for what they are and only use them for FT practice.
I refuse to accept a lower yield due to straightness. Before I make up arrows from a dozen shafts, the first thing I do is check straightness. Guess what... If I find any shafts that are outside the tolerances
I PAID GOOD MONEY FOR they are going back to my dealer for refund or replacement and he can take up the issue with the manufacturer. If I pay for +/- .003 straightness, I' m not accepting +/-.006. And I have no problem burning up more money in gas than the price of the shaft in order to get what I paid for.
