What is the most used bat in college softball composite or aluminum?

In the 2011 World Series College Fastpitch

1) Demarini CF4/CF4 Insane

2) Easton Stealth/Synergy

If I bought anything else it would be the USA made Anderson bats. All metal! The kids I've seen using these bats, don't seem to be miss anything.

These two were the most used. My 14 year old swings the Synergy Speed 33/23. The weighting and balence works for her, big girl! She pounds the ball.
