Ground Strap vs. Ground Cable

Belt and suspenders. You will never have TOO good of ground, just like you can never have too many outlets.
But as was discussed you can have too many grounds.

BTW for those who want a good flexible ground cable, check with welding supply houses; the ground cables used for arc welders usually uses a very fine wire and is a very flexible cable type versus the coarse wire cable used in most ground cables for cars. Welding cable also has a very chafe resistant outer jacket, as it is made to be dragged around on the ground.
This usually prompts a discussion about how welding cable isn't intended for oily environments and the high heat of an engine bay. My local battery shop sells Carolprene cable for use as battery cable. See attachment, I've no worries from using this cable anywhere on a vehicle. I use cast lugs (no open ends) with adhesive lined Heat-Shrink to bradge between the cable's insulation and the body of the lug.
