I am at the thought if a girl can swing one 20oz bat and not another 20oz bat because it is a heavy 20 oz then she could really use a good hitting instructor. Of the dozens of fp bats dd has tried and the several we have owned, ONLY rockettechs felt heavy per oz to me.
Aded some scale weights to the photo on page 1 for those curious.
Also, to OP...I have a nice Stealth SCN5B FS if interested. 30" and 20.56 oz. Quite the hot bat but both daughters have outgrown it and swing longer Stealths now.
