I have a f21 in a 30", it's just still a little too long for her. I don't know about lack of demand for 29" bats, there's a crap ton of 8u players and small 10u girls swinging 29" demarinis and louisvillesI had one in a 30” that I got from @CoreSoftball20. The barrel length seemed pretty small compared to other brands. I wonder if that has something to do with them not making a 29”?
