We are doing something very similar. We too have a rotating turret with the balls running up the middle, so we can't run the wire there. We are putting all our wires in mesh tubing type thing (sort of like a finger trap), and running them together to a single point on the turret. To deal with the loose wire, we are using a tool balancer from McMaster to pull the loop of wire down.
We did look into slip rings, and they were extremely expensive. I'm not sure there's a huge benefit to having unlimited rotations anyway. As long as you have 370+ degrees of rotation, you will be able to aim in any direction. Simply "untwist" as needed.
