Maybe you oughta try a good old fashioned paper tune!
Mr Fritz... I save the paper for when nature calls. It's a heckuva lot more useful for that than it is for tuning bows.
I can tune a bow to shoot an aluminum arrow with acceptable flight and accuracy, even decent paper tears, within 10 minutes. Fine tuned within a half hour. I've pissed away HOURS trying to tune carbons, with every tuning method and trick I know.
I require arrows that are 32" long MINIMUM. That doesn't leave me anything to cut off a carbon shaft. Have you ever checked the ends of raw carbon shafts for straightness? There is simply NO WAY to tune arrows that are crooked. And, believe me, they are crooked. Anybody that say's "carbon arrows are either straight or broken" has never checked them for straightness.
If my bow was dragged, bumped, and scraped for 150 feet over rocks, dirt, and other debris; and then fell and tumbled another 100 feet, it would not matter if the shafts in the quiver were made of titanium metals used on space ships. I would not be firing the bow.
Not only might the bow be all screwed up, the sights and other relevant gear might be totally out of sync. Mostly, I would wonder, and be real concerned, about which carbon shaft or shafts were slightly fractured and is going to blow up in my face when I shoot one and end up in my arm and in a main artery, or permanently damage nerves.
C903, exactly what I was thinking!
