Take a look at the Nike Torque bats. I've had the opportunity to hit with lots of metal bats over the last few years and that has been my favorite of all. In my opinion, I prefer one piece bats so I would also recommend the Louisville Exo-grid, though I've only hit with the first generation white one. I think that you would be happy with either of those, and would also save a little cash since they are a little older. Our club team had DeMarini bats so I have swung all 3 of the ones you listed. The CF3 is composite, so you get more of a thud than a loud ping. Also, its more end heavy than most aluminum bats, almost weighted like a wood bat. The De Marnini Voodoo, and CF3 are solid, but I still would say that you should give the Nike Torque a shot.
