Sorry for the delay in answering this, just got too busy.
As far as the short goes, I stated I assumed it could short on C23, but I have never taken the time to look closely. My experience is that it WILL short on a CGO3+, because there is a metal plate on the top plate just above where the wires come out of the bottom gimbal plate, This will short if you use the round dampers.
However more important than the potential short, is the design of the damper. Dampers are designed with particular characteristics in mind, like gimbal/camera weight and mass,
@PatR,
@Phaedrus and others are far more knowledgeable than I am in this area and can hopefully speak to the problems of using the wrong dampers. This is just such a case. The ball dampers were designed for a lighter smaller 2 axis gimbal/camera, and being much stiffer could introduce vibrations or jello. Maybe not, but I would strongly recommend using a damper that was designed for the camera/gimbal. This is why I chose to use the C23 damper with foam instead of gel, because it is more compliant than the round CGO2 and the 3-rib CGO3+ dampers, and was designed specifically to suspend that particular weight mass combination.
BTW, foam filling eliminates the stretched look of the gel filled damper.
