How do you determine the correct Helical for your arrows? I mistakenly picked up a "straight" Arizona E-Z fletcher and have been using it for awhile now. Last night, while shooting at about 40 yards I noticed the my arrow flight is a little goofy. I'm still hitting where I'm aiming, but the arrows have a strange flight pattern.
Is it better to use a left or right helical? If so, how do you determine which and how much to use?
