Manfrotto has it's own proprietary quick release design. I have one of their fluid head and just like what Don showed on his camera, it has a large footprint. I mounted an Arca-swiss compatible clamp above it so that I can use my arca swiss camera mount and lens mounts for easier and more solid grip. I even have a smaller camera mount for my point and shoot. With the arca-swiss mount, even an inch of grip will provide a solid grip whatever it is holding. I know this because it is what I use, I've tested it and I am a believer with these products.
I use the Markins PG-50 which has a universal fit for any Nikon camera and battery grip.
Re: 70-200mm f2.8. I added an extra lens foot so that I can use it on my ballhead.
If you are looking for a really solid ball head, look for the RRS BH55, Kirk, Markins or Arca Swiss Z1. These are the best ball heads around.
You can go with a simple set-up or customize it like what I did. This is just to give you an idea.
