Compared with ball heads, the Manfrotto XPRO Geared 3-way head stays put after being adjusted. While ball heads enable the speed and ease of making adjustments in all three tilt, pan and swivel directions with a single locking knob, they typically tend to sag a bit after tightening the clamp and releasing your grip on the camera. You can experience the same kind of problem with a conventional 3-way head, albeit to a lesser extent.
