Please forgive my lack of understanding of this process. I mentioned it at our local archery shop and they said it was a waste of time for modern compound bows. So exactly what am I looking for when bare shaft tuning? An arrow that enters thetarget perfectly in line with its path of travel, I would assume. At what distance? And if the arrow angles into the target pointing to the right (for a RH shooter), is that a sign of too little spine? Thanks.
