Let's cut to the chase, my favorite bat brands:

1.Rawlings,VELO,5150

2. Louisville Slugger,Assault 

3. Demarini,CF7,CF8

These are all great bats, they all hit bombs. I put Rawlings first  just because they are the most balanced.I put the Assault second because it hits bombs but it is not the most balanced. I put the CF8  third because it is a balanced bat, but since I am so used to alloy I think the composite is too soft. But they are great bats that I have used.
