The Dudleys SSUSA absolutely mashes the ball. These bats do require a little bit of break in after service due to the Kevlar shell. I suggest hitting 44/375s till it loosens up. The Lite Frame Technology (LIFT) will allow every player maximum bat speed at impact.The 12 Barrel End-Loaded model is for advanced players that consistently drive the ball and want more mass at the end of the bat. Approved only for Senior Softball. The item "SSUSA Dudley Lightning Legend Lift Endloaded 25oz Softball Bat" is in sale since Thursday, April 29, 2021.
