Really appreciate all the help and info—thanks Todd!
So, yes, I originally thought of trying to mount the whole shebang with fluid head, etc.
But then when I saw that setup (and know how freaking successful those videos are), I started leaning towards the leaner, more elegant rig. I only have prime lenses for my DSLR (Nikon D810), but I should be able to just raise or lower the c-stands to get the right framing.
I did some looking around at Matthews, and saw some speed rail options, and I think I might have found the clamp that they used at Tasty. Does this look like it?

It’s called a backdrop ear.
And would you recommend a thickness for the speedrail? Looks like they come in 1″, 1.25″ and 1.5″.
Thanks again!!
