This year at 99BATS, we decided to take all of the most popular models that we carry and compare them side by side. Today we're going to take a look at the size of the sweet spot on the barrels. As you can see from the picture above, we lined them up side by side and slid a "donut disc" with an inside diameter measuring 2 9/16" over the barrels. Since the maximum barrel diameter of these BBCOR bats is 2 5/8", the disc stops just before the largest part of the barrel.
