You can get really cool "Club Scene" type shots with this light and a low to medium flash output. Essentially you would use this slow shutter speed of 1/30, decrease your ISO to or a little under 1600 and an aperture of around f/4 [this is experimental and will take some shots to narrow it down... depending on your "club" lighting situation and amount of background you choose to show] and camera WB set for daylight/5500k. A low output will result in a quick/short pulse from the flash which will "freeze" any action with that illuminating pulse in daylight true color. Because the shutter is open longer than the pulse, [your exposure is longer leaving the shutter open a bit after the pulse] you will get cool people blur and deep warm colors from the club lighting!!! Be sure to hold the camera steady as you can through the entire exposure [ don't drop the camera from your eye immediately after the flash]. You CAN ALSO ~MOVE~ the camera during that exposure time when the flash hasn't fired and you would get REALLY cool streaks of blur and dancing lights!
With that said, I would recommend using a "snoot" on your flash as that will narrow/limit the flash beam to the center of your image and no spill will fill the dark club scene!
