It is a totally different maneuver depending on whether you have reverse or reg camber. On my camber board it's all about using your edges, switching back and forth between edges while you spin. Being comfortable doing switch is essential to doing that since you will be turning the board while in switch.
Reverse camber its basically about keeping your weight on the tip of the board that's in front of you, while keeping the tips flat and using your hips and shoulders to rotate.
