The last time a ball in this line had a hybrid cover was the Mastermind Genius from early 2014. In sticking with the Einstein theme, this ball’s new cover is called Relativity Hybrid Reactive. We felt that it gave us more traction in the oil, which helped to smooth out the overall reaction shape a bit for our testers.
