The Thunderbolt M/D gives you the same devastating power of the Thunderbolt because it has the Thunderbolt's dynamically-balanced Power Core. And it's packed in Ebonite's exclusive new M/D cover, which contains a special additive that makes it hunt down the pocket and hit harder with less deflection on medium to dry lanes. Roll the only ball for medium to dry lanes that combines maximum power with maximum control.
