less clothing on the model? 
the video was a good primer. Maybe getting into the power levels on the Einstein would be helpful to some, and the differences between diffused vs beauty dish type light with no diffuser.
For the speedlight, i bet most users would be interested in bouncing light/reflectors and maybe the power levels there too. I imagine the speed light was up around 1/1 while the Einstein was cut way back. Folks might find that useful.
off topic a bit, but one thing i have been looking for is a good comparison of brackets for speedlights, small bare bulb lights and monolights etc. I've always just used speedlights but find myself needing more power and want to step up to the Cheetah 360. I can't afford to get stuck with equipment that only works with one kind of light or needs a two hundred dollar rig to mount another light.
