Canadian Pilot, the speed hunting is down to how the aircraft is manging the climb. In V/S mode in an Airbus the autothrust is managing the speed and the vertical speed is being managed by the elevator.Iam surprised by your assertion of hunting as the aircraft does everything at 1g, which is meant to be very smooth. The FBW is meant to be flown as an integrated package so reverting to manual thrust just doesn't make sense to me .I doubt that your method is any smoother than just selecting with a bit if finesse a vertical speed of 1000ft min.
