Thanks to a new material developed exclusively by PACIFIC called PolyCite. Unlike other monofilament strings that have only a linier/single molecular chain to equally support the energy in and energy out, PolyCite molecules are arranged in a multidimensional chain whereas upon ball impact, some molecules are receiving the energy and others are storing it; resulting in 25% greater energy returned to the ball. Optimal spin potential is an added bonus and the tension maintenance in unmatched.
