What is the Correct Spine for an Arrow?
The most important consideration in choosing an arrow is the spine or stiffness of the arrow. Generally, the heavier the draw weight, the more spine the arrow shaft should have. There is a lot of material out there on arrow spine, but the even the most educated person can only guess at the correct spine. Four factors come into play when choosing the right arrow. If you use a Fast Flight string vs a Dacron string you will need to decrease the amount of spine. A heavier field point acts as an opposing force to the arrow causing it to bend easier. More spine is needed in this case. The shorter the arrow the less spine required. And more spine is required for longer draw lengths. If this all seems confusing, don’t worry. I don’t get it either. My advise is to go to your nearest retailer and look at one of the arrow selection charts availabe. It factors in many variables and helps reduce the guess work. Whatever the chart suggests, I recommend starting with the next size down. Almost always
