Everyone needs a big brother right? Even as good as the J3 ASA bat did in ASA we teamed up with DeMarini to come out with a better version for the competitive player. We have stiffened up the handle, added some end load and kept the rocket launching barrel and done a tweak here and there. DeMarini has come up with what they call "Bad Ass Technology" and our testing concludes they named it appropriately! Barrel: 12" Stacked Composite. Handle: SC4 Alloy. Slight Endload. Newer version of last years Cluggy!
