Question for Bat Geeks
The new Louisville Slugger Super Z1000 has a "Mass Index" sticker on the plastic wrapper.
It's arranged like a matrix with lower numbers at the "Control" end of the chart and "Power" numbers at the higher end.
Never seen these before, anyone have any idea exactly what they mean?

Question for Bat Geeks
Mass index is LS attempt to quantify moment of inertia (moi) or amount of endload in the bat.
More endload provides more momentum to collision with the ball if able to maintain the same swing speed.
More balanced ( less endload) usually allows for increase in batspeed.

Generally the two are inversely proportional.
As endload increases, batspeed will decrease with little change in total momentum delivered to ball.
...so finding the number that you are comfortable swinging will likely provide the best results.
Finding the mass index for bats from other vendors will help compare inertial properties.... the difficult part is getting everyone to use the same scale.


IMO
