My 10 YO DD is small 4'5" about 65 lbs with a quick bat. She's been hitting a Miken Halo Light 29/16.5. I've noticed that it seemed like she was maybe overly quick with it so I pulled an old Easton aluminum 29/19 out of the garage and she started crushing it. So I'm in the market for a new bat. Should I try and push her to a 30/20 or go with a 30/19 or 29/19. Hopefully she'll grow, her sister who is 20 mos older is 5'3".
