Took my 12U DD out to a local park to compare her new 2020 LXT (31/21) vs her USSSA Ghost (31/20). The bats are pretty close in weight. Backed up a pretty good distance from a 16' fence and compared how many she hit over with each. It was pretty much a draw. Both of these bats are pretty hot. I wish I had a Ghost 31/21 to compare the LXT too. Her teammate had one but it cracked in the last tournament. I might have to buy one from Core and update this comparison. She does have a USA 31/20 Ghost. We might give it a try. She just didn't have it with her.
