My oldest daughter (15U this coming season) uses a 2005 Rockettech (32/23) and my middle daughter (12U this coming season) uses a Miken NRG (31/21). Obviously the Rockettech has great pop, but the Miken has excellent pop for a balanced bat. The oldest daughter does a great job of not letting her hands drop and the Rockettech has been great for her, I have seen some girls not able to use it because of the tendancy to drop the hands. The Miken seems light, but my daughter and a few on her team last season used this bat and it was pretty good. Plenty of pop...
