Motiv says this about the Tank covers, they call it a special urethane. Is it a hybrid urethane mix? Like my Shadow Ops being a 80% urethane and 20% resin?
The Tank™ series changed forever with the introduction of Microcell Polymer technology. While Microcell Polymer (MCP) is now recognized as the solution for the ball motion gap between reactive resin and urethane, MCP does not replace urethane completely. With that in mind, MOTIV® has been in pursuit of a truly special urethane cover stock that provides adequate traction on modern lane surfaces conditioned with the high volume, high viscosity oil patterns competitive bowlers see so regularly.
