Thank you! It was a rather simple setup. A Digibee 800 on a boom with a 36" white shoot-thru umbrella, a 36" white reflector on the opposite side, triggered with Cybersync transmitter. The Digibee was set to about -3.00, so recycle time was pretty quick. I was able to occasionally fire my D850 @ 7 fps and had very few dark frames. She was in a good mood and very cooperative. It felt good to be shooting again.
I also have Paul C Buff DigiBee DB800 strobes (two of them). I like that they're compact and have a powerful LED modeling lamp. The recycle time is 1.5 seconds for 100%. It's 0.5 seconds for 50%. Firing your D850 at 7 fps is a little fast. I've always just had my camera in single shot mode and waiting a couple of seconds between shots.
Did you get their model 7UR umbrella reflector? It spreads out the light 180 degrees to better fill umbrellas with light. I use one when I'm using umbrellas.
