A lot of girls arond here feel like the 2013 has more of an end load. Many of them are trying to eat up any 2012's they can find with the new USSSA stamp on it because they dont want to have to move to the 2013.
no differences at all as far as performance in the 12' & 13' insane. Three things are diff. 13' has the new USSSA stamp on it and the 12' my dd has does not have it, it is red, not orange and on the knob of the 13' it is not the same as the 12'. My dd likes the 13' better than the 12'.
No real difference. WITH THE DEAD LINE MOVING UP AGAIN TO 9/1/14 you'll get 2 seasons more out of the bats. You can get a new 2012 cf5 in the wrapper for $179. I would go woth that over the 2013 for $299
