You can't use a flat, tinned copper braid for a ground strap?

I could, but there's no means to support the length of braid as it
uncoils. If it sags onto the fixed equipment, there will be a snag.

The ONLY reason we elected to go with the bronze is because in simple
tests, it would self-support from just one end for a distance of about
6" from the support point.

If we had any means whatsoever to prevent the coil from sagging when it
loosened, I'd be using stainless steel braid with crimped fixturing.
