Spine Chart

The purpose of this tool is to provide a simple point of reference for testing. 

By entering your draw weight and total arrow length a chart will be generated providing approximate spine needed for various total weight up front.  "Spine A" & "Spine B" is providing a high/low range for you to evaluate based on how aggressive your bow is, exactly how much weight you plan to have up front, etc etc

Again, this is for reference only, and is best utilized to help choose an appropriate test pack for you to determine what works best for your specific setup.
