Actually, there’s a reason to NOT use braid; from the ABYC bonding standard:

Copper braid shall not be used for this purpose. > > (a) Common Bonding conductors fabricated from copper or bronze strip shall > have a minimum thickness of 1/32 inch and be no less than 1/2 inch in width. > > (b) Wire, where used as the common bonding conductor, shall be at least no. 8 > AWG. > > Note: These requirements are based on both physical strength and the ability > to make alld maintain low-resistance connections, as well as current ratings. So 8AWG would be okay for bonding; UNLESS it’s part of a lightning protection system. Then 4AWG is recommended.
