I agree with Peter and Raymo. An additional 1 kg weight to the two 5kg is all that is needed to balance the 8inch newt and camera on the HeQ5. That is what I use .
The mount should not shift or move suddenly unless what you are seeing is the beginning of an automatic meridian flip. The dovetail clamp on top of a heq5 can come loose if the grub screws are not tight but that does not sound like your problem.
