Lighting on location with speedlights

I've been experimenting with my speedlights to understand their full capabilities. Last week I went out with the guys in a lighting class I'm taking, in midday with extremely harsh sunlight, with the plan of overpowering it with flashes. After using a proper strobe, we tried a similar setup using a pair of Nikon speedlights (an SB-800 and an SB-600) fired using Pocket Wizards. Since I was using my old D70s, I realized I could sync past the 1/500th that's published as the official sync speed. I'll write a full post soon with the details, but the result was really encouraging. The above shot was done using just the speedlights as a test. Thanks to the teacher for posing for us!
