#511 Gold Tip/Carbon Express Adapter Weights:
Gold Tip/Carbon Express Adapter Weights. This system makes it possible to not only add weight to the shaft, but also to change the dynamic spine of the shaft to fine tune it for perfect arrow flight. Adding weight only to the point end of a Gold Tip or Carbon Express (excluding the 75's and 90's) causes the shaft to have a weaker "dynamic" spine because the arrow is "pushing" more weight. Adding weight to the nock end (#510 Nock adapter need for Gold Tip only) causes the shaft to have a stiffer "dynamic" spine by absorbing more of the bows energy.
Combo Pack comes with 3 dozen 20 grain weights and 3 dozen 50 grain weights which is enough to add up to 210 grains per arrow to one dozen arrows.
Sold by the Dozen or Combo Pack.
