I like turrets. These past two years, I think a turret has been/will be very useful for teams to use. I think that because it gives you tons of degrees around so you can place objects better and more efficiently. Sure, maybe I'm a bit bias, but I have not noticed any major mechanical problems with the turret we used last year...and so far this years. In my opinion, I think turrets will play a major role in who comes out on top. Viva la turret!
(If anyones team has a turret please PM with a link to your site or a place where I might be able to see a pic of it.)
