have heard of folks using the bare shaft method to determine how close an unknown arrow might be to ideal spine. Any comments?
For traditional archers , shooting off the shelf , with a finger release .
Cutting an inch and a half off an arrow greatly increases its spine , or bend/flexibility in other words . Put fixed broadheads on both length shafts and you will see , they hit different spots left to right , as most compound bows have cabelrod toqure , and grip toqure issues .
