Better option than a ground strap?

Has anyone done something to replace the original ground strap with something more robust or mount to a new location? Mine has looked pretty rough for a while now, and I've got a fair deal more going on electronically now that I have a modern engine and other stuff installed. Everything important or high power has dedicated grounds to the engine block, battery, or a small terminal strip I have by a fuse/relay box I added, but several things still rely on body grounds to work (like lights, gauges, etc.). I'm wondering if there is a reason to use the firewall as a grounding point vs something more robust like tying directly from the battery to the core support or something like that. Just feels weird to have a small little self tapping screw be all that connects a lot of various things back to ground. Looking for a way to modernize it if there are better options. I had considered just welding a bolt somewhere to use as a body ground stud as well, but haven't gone that far yet.
Talk to Tony at CE Auto Supply. I installed his grounding kit when I relocated my battery to the trunk. He's a car guy too so very knowledgeable and a great resource for "why do this"...
