Bowstring Tuning

Bowstring "weight" can have a significant effect on arrow spine. Increasing or decreasing the number of strands in the bowstring can influence the arrow's dynamic spine enough to require a shaft size change of one full size weaker or stiffer. If your arrow reaction is too stiff, decrease the number of strands in your bowstring. If your arrow reaction is too weak, increase the number of strands. Serving weight (center serving) can also produce the same effect. For example, monofilament center serving will cause the arrow to react stiffer than lighter weight nylon center serving. Simply changing from a metal nocking point to a "tie-on" nocking point can have a noticeable effect on arrow spine, due to the weight difference between the two styles of nocking points.
