You want to win, and you need the right equipment in your arsenal to do so. With two of the best coverstocks in the GB cover series (10.7 and 11.7), the Hard Ball and Curve Ball pack a one-two punch the pins won’t forget. If you need a smoother arc, go with the Hard Ball. If you need a more defined curve, go with the Curve Ball. Go with both and you won’t go wrong.
