The Zing features a new core design based on the Katana concept, and we feel it’s a more dynamic version of the Katana core. The adjustment to the dynamic properties gives the driller more options without using any balance holes. The Zing is wrapped with the Forged 2 cover, a cover we originally featured on the Slash and Conspiracy. The Motion of the Zing is what we have all come to expect from Radical; it is very aggressive off the spot, creating a big backend motion. We have also incorporated the hard-hitting DynamiCore technology. DynamiCore increases the coefficient of restitution, and this means that pins leave at a higher rate of speed. Faster pin speed will yield a higher strike percentage on off hits.
