It's a good bat. I bought a 32in/20oz for my 11 year old. It was a little big for him but it will be perfect next year. These are a bit expensive for little league but there definitely is a noticeable difference between this bat and the less expensive ones. You feel it when you hit a ball.
If I had to do it again, I'd probably go with the cheaper bat and only invest in the better bats when they get towards high school age. That's not a knock on the bat, it performed well, just not sure it's worth it when the kids are rarely hitting the ball out of the infield.
