Hello, I need some help to get a servo for a Ball and beam proyect:

I have tried with HS-805BB because I need much torque, but it has too much looseness.

I use the servo to spin a 1 meter beam and it acquires inertia when it moves from a distant angular position.
As a consequence of this inertia, the beam bounces once achieved the desired position.

I want to cushion that bouncing as much as possible and I thought I could do it by changing to a servo:
- With metal gears instead of nylon gears.
- Of a smaller scale as smaller gears may have less looseness.
- Digital. As digital servos have more accuracy than standard ones, they should have less looseness.

Although I don’t need as much torque as I have with HS-805BB I need a strong servo.
What servo or kind of servo do you recommend me?

Thank you for the attention,
Raúl
