Demarini Big Barrels

Almost every poster here has son's using -3 BBCOR bats. I recommend you try a site like BASEBALLFEVER.com. In the Baseball 101 section are many posters with preteens like yourself using big barrel, large drop bats. 

What is your budget?  You can spend $300 on the CF composit or $150 on the vexum.  I think the cf is more balanced.  Good luck.  

Voodoo is end loaded

Marucci Cat 5 (-5)

The voodoo is a nice bat, but as stated it is somewhat end loaded.  It is a little soft in the handle, so for a contact hitter it works pretty well.  You need to swing one to see if you like it.  I think they are on sale these days as well.
