The reason why you might not find much information on that is that the smaller the radius, the higher the force in the cable, which is theoretically good, as you would need only a relatively small pulley on the gimbal for the same final torque.
...but also, the higher the force in the cable, the higher the force the bearings need to hold. If you increase this force too high, the bearings might fail fairly quickly.
And I am not too keen on how easy it is to replace the bearings inside the motor.
The pre-tension you need in a cable drive is also higher than in a toothed pulley drive.
