If you find that you need more tilt than you can get with just the monopod then you might want something like this.
If you are using to steady a body instead of a big lens and need rotation then buy an L bracket for you body to fit in the arca-swiss clamp or get a camera rotation head like this.
I have never been fond of any kind of head that allows you to put the camera in portrait mode that also puts the camera to the side of the monopod. Doing so defeats the support aspect of the monopod when the weight is not centered over the monopod. With long lenses it is easy as the generally come with a lens collar allowing you to rotate the camera and lens combo.
