Easton XL3 Swing Weights for 2 1/4 vs 2 5/8

2013 XL3 2 1/4 Barrel

If a player prefers the XL3 Easton Power Brigade bat and plays in two leagues that allow different barrel sizes, how does she find an equivalent swing weight in one barrel size versus the other?

I suspected that two bats from the same company (and same XL3 line) would have very similar swing weights at very similar total weights. I found these two bats in similar stated total weights and measured their MOIs. A 20 oz XL3 bat, regardless of barrel size, would, I thought, have a pretty similar swing weight to any other 20 oz XL3 Easton. Or so I thought...

It turns out, remarkably, bats in the easton XL3 line with different barrel sizes (and lengths) but similar total weights have very DIFFERENT swing weights.

2013 XL3 2 5/8 Barrel

I measured the 31 inch 20 oz 2 1/4 Easton XL3 with its 20 oz 2 5/8 counterpart. (Youth bat vs Senior bat). The youth bat (2 1/4 barrel) swings almost a full 15% heavier (at the knob) than the 2 5/8 XL3 version of the same total weight.

Remarkably, the stated weight on these two bats from the same company have nearly nothing to do with their actual swing weights. Proving even further that total bat weights mean pretty much nothing. 

As a result, if you need a different diameter bat and are trying to find an exact swing weight in the line you like make sure you drop an ounce or two (atleast) in the thinner and longer barrel version. If you have access to the bats you can also use the calculator to find an equivilant MOI bat.
