I'm told it's got more pop. Our team has one and it's pretty nice. Also, our coach said that it takes a couple days of hitting with it to "break it in." I've never heard of that with a bat.
We've had ours for a little over a week now and the ball is jumping more than it was.
Just a heads-up: It doesn't sound like a metal bat.. it sounds almost like a wooden bat or a very dead metal bat. It doesn't sound very good, but the ball jumps.
