I have great results with a Manfrotto joystick head (222) on my Manfrotto compact monopod (479-4/LA24). The joystick does not produce gentle & smooth movement, but gives all of the motion required. If you need long exposure times, you can get better support by angling the monopod towards you - place the foot of the monopod about 12" in front of your feet - the top of the pod leans against your chest and the head itself gives the camera attitude you want. The joystick head also allows you to carry relatively big/heavy lenses with ease. The head will go to 90 deg from the monopod, and so the lens becomes parallel with the monopod. You use the joystick head as the handle, and both the pod and lens hang straight down.
