The little league 11" balls have a low compression. At this age most of the girls aren't strong enough to compress the ball into the trampoline effect. Which is why I say alloy. Soft ball with hard bat= recoil or hard ball and soft bat= recoil. Soft ball and soft bat= dud.
The higher the compression factor on the ball, the softer the bat should be for optimal performance.
A 325 or lower comp. ball will recoil harder off an alloy bat. (The ball compresses and not the bat)
A 375-400+ ball will recoil harder off a soft composite bat.
Ball comp. definition: whatever the number is, is the compressive foot pounds required to egg shape the ball 1/4".
