MCC (Mongrel Composite Construction) is used in the handle, which gives added durability and strength that is needed when using Titanium enhanced alloys for the barrel. * RPT (Resonance Proof Taper), an ancient Combat secret, which, when combined with Gear Technology provides for zero sting and vibration in a two-piece bat. * TEA (Titanium Enhanced Alloy) contains trace amounts of titanium and other elements to deliver incredible strength. * GT (Gear Technology) has a special taper in the barrel, which provides a softer feel and greater performance. * Approved for play in LLB, DIXIE, PONY, AABC, BABE RUTH, and USSSA.
