I just read the thread you referenced. When running Battery cables, I use "1-ott" welding cable. You can get it from a good weld shop. It is also pretty inexpensive. While you're there, get some appropriate size copper lugs crimped on to the ends that get terminated with bolts or screws. (You have to plan ahead a little and have your lengths determined) For the battery lugs, purchase the type that you solder the battery cabling into. Your auto parts store should be able to set you up with a solder kit to do this. (You use a propane torch)
Finally, apply heat shrink tube over where the lugs meet the wire. this will help avert corrosion and it looks damn sexy to boot....
I'm sure some will think this is overkill, but D.V. has had great success running the ground wire all the way from the battery negative to the engine block. I have followed his advice and never had a cranking problem.
