Due to the weave of the braid, thus the bends in each individual wire, the
inductance of a 1" wide piece of braid of a given length will be greater
than the inductance of a 1" piece of flat copper of the same length. For
low inductance ground circuit applications where movement is not required, a
flat material such as strap of copper is preferred to the same width of
braid. A round conductor is almost equal to a flat material and is
typically easier to use where slight bends are required. In any event,
large radius bends are preferred over small or tight radius bends.

Why is braid to be eschewed especially inside the shack?

I can try removing the external ground. I currently have 3/4" wide
single piece of braid going from the radio to the PS to the amp to an
outside ground (total length from last unit in line to the hole in the
basement wall is less than 5 feet).
The proper bonding is CHASSIS-TO-CHASSIS of interconnected equipment. One
of those chassis MUST be bonded to the power system green wire, to the
antenna system entry panel, to the power system ground, and to all other
grounds in the building.
