34-inch titanium bat, LOUISVILLE CATALYST II model. - Brand: LOUISVILLE - Model Name: CATALYST II - Material: Titanium - Length: 34 inches - Weight: 710 grams - Balance: Semi-top Used in weekly practice and official games with a 3-year hardball. The feel is hard, with a resonant sound that feels good. Being semi-top balanced, it combines the easy swing and distance of both mid and top-balanced bats. The bat is in good condition. I took care of it after every practice and game, so I checked its condition each time. Please feel free to purchase.
