My two cents- DD (8th grader- a strong 5'7", 150lbs)) has Axe bat, DeMarini Cf4, and now new Xeno- all 33/23. After adjusting to the different load of the Xeno, compared to the CF-4 I can tell you I have NEVER seen her hit the ball like this. DD with CF 4 hit HR over 210 ft fence- but ball was floating and trajectory carried it. With the Xeno- balls FLY off the bat, hit very hard with solid contact and difficult to field even ground balls. Scared for the infielders.
