This is just a list of what I recommend for those wanting to do off-camera flash with the Nikon TTL system and using the PocketWizard radio system to fire the flashes.

You can substitute another Nikon TTL or off-brand to lower the price.

CowboyStudio Flashlight /Hot Shoe/Umbrella Holder with Swivel/Tilt Bracket

Here is another metal bracket option.  I own both of these and find they work equally well.

Interfit Metal Umbrella Bracket with Adjustable Flash Shoe

Manfrotto 5001B Nano Black Light Stand – 6.2′ (1.9m)
I chose this light stand because of how small it folds up [19.3″ (49cm)] for easy travel through airports.

PocketWizard MiniTT1 Radio Transmitter, FlexTT5 Transceiver and AC3 Zone Controller Bundle – Nikon
The AC3 helps you control the flash power from the camera and attaches to the Mini TT1 on the camera. The TT5 fits on the flash and the light stand.

External Flash Battery Power Pack for SD-9A Nikon Speed light SB910
Whenever you shoot with Nikon Speedlights, you cannot shoot continuously forever. It would be best to shoot in small bursts of under 10 frames at a time to let the flash cool.  If you do not, you will send it to Nikon for repair. The external battery will just give you more flashes, which is how I use it rather than shooting faster.
