We are adding a turret for two reasons:
- We've done it before, easily.
- It involves software to aim well, but you can also manually set our turret and shooter assembly for autonomous mode this year.
If either of those things weren't true, I would support a non-turreted shooter for my team. We just did well last time with a COTS lazy susan type bearing setup that we're refining for 2012.
There's rarely a question of "best" in FRC. There is only "best for your team". That said, a turret for many ball shooters is a decision with a much lower opportunity cost than, say, a swerve drive. Thus you will likely see turrets at the top of play no matter what.
