There is nothing similar out there. Those were balata covered wound balls. Solid core balls are the only thing you will find anymore. Cover material is different too. The closest thing you will find to the old balata is the ProV1. That's the reason Bubba Watson went back to it. He loves to work the ball and it gives him the best feel and maneuverability of any modern ball. That said, still way different from the old wound balls.
