Am I correct that this is the "ideal" reverse return design for a small, one-level system? Great balance, minimum material in the mains? And that the overall size of the "loop" is determined by the layout that allows the branch runs to be as similar in length as possible?

The first rad fed is the last returned, and vice-versa. This equalizes piping lengths to all rads.

reverse return

I do all manifolds and remote manifolds reverse with my tubes in reverse return just out of habit. That's how I was taught in my solar days piping in panels and multiple storage tanks. I've seen floors on service calls that weren't piped in reverse return with cold spots from unequal lenghts of tubing. I try to keep my tube lengths within 5% of each other off the manifold to my floors and with reverse return, have never had a problem in 20 years. I think it's a good habit to get into.
