No vibration like Easton bats.
For an 11u
I bought this bat for my little leaguer who I figured could use this as a batting practice bat like the pros do, a heavy bat for practice but in game she would use his neon green 2018 Quattro. This bat has been his go to and he leaves the 2018 model at home. It’s got great pop and no vibration. All of his teammates like the heavy weight in the barrel and hits shots to the outfield with it. My son is small for his age but is strong and gets this bat around just as easy as kids using heavy 30 inch bats. Yes it’s heavy, but more mass should produce greater velocity given its MOI and solid construction. I can’t really find a flaw. My son loves this bat and is driving the ball into the gap with enough room to spare.
