As this was my first time taking real action under some colourful spotlight, I have to experiment. Initial shots were blur because the shutter speed was too slow until I crank it up to 1/1250 sec. Only then I manage to "freeze" the action. Nikon D3 f/2.8 1/1250 sec ISO-1800 EV: -2.7 70MM no flash.
The two photos above were not retouched other than cropping and resizing. There is no noise/grain visible.
