Last year their was a kid on my sons team that used one until they found out they can use them in games. He could put it in outfield with the bb. Put a regular bat in his hand it would roll to the outfield. The bb has alot bigger sweet spot. My son started off with a composite bat. Had to get a new one after he made solid contact on a 40' night. He cracked the bat and he ain't a real big boy. Found out its not uncommon
