The more accuracy-enhancing technologies a shaft has, the bigger the number on its price tag. Micro-diameter arrows, for instance, cost the manufacturer more to make, and these shafts often showcase the manufacturer's top-end arrow technologies. Don't skimp on quality, but don't think you have to take out a second mortgage to put an arrow through the lungs of a 40-yard whitetail. Match the quality of arrow to your hunt and the accuracy expectations you put on yourself.
