My kid once had one of those bats. It was 11u on the 50/70 field.
I have a video of him hitting a home run to the opposite field. It's not a pretty swing. He was late, out of sequence and off balance. But the second the ball hit the bat, people in the stands screamed "home run!" And the ball flew well out of the park - - to the opposite field!
It was ridiculous.
I knew then that a swing such as that one was never going to work on the big field and against better pitching. And, starting with 12u, it was time to start worrying less about the bat and more about the swing.
Fast forward to High School. Using a BBCOR, my son led the varsity team in homers as a freshman. Meanwhile, kids who used those hot bats with incorrect swing mechanics back then and who never changed are all out of the game or riding the bench as back ups to the back ups.
