You must of been so proud seeing her hit that bomb, congrats!
Just curious, if she hit the ball 230ft with the Xeno 32/21 why does she need a different bat? Can't argue with that result. My daughter as well was using a heavier bat this year with no effect on bat speed, her coach thought she could handle it, no problem. However something did not look right to me. With faster pitchers she couldn't hit the letter high pitches and she was unable to adjust/correct to other pitches. I told the coach, my wife and my daughter that the bat is too heavy for her, they all disagreed, of course. Finally I proved to my daughter she would be more effective with a lighter bat, I bought the bat the next day. She used it in her grand championships and was fantastic, coach asked what took me so long to buy her a new bat, LOL.
Point is, why change? Obviously she handles the 31/20 well
She may not change she may ride out the fall ball with her 32". That homerun was off of a high pitch the previous pitch was perfect down the plate I gave her a what are you waiting for look??? She told me afterwards "Dad I knew that HR pitch was high but it was like slow motion so I said I'm just gonna go for it"
