I'll sell you some extra 1/0 wiring if you want to make more grounds. I'll sell it for cheap and I bet it'll be infinitely better than straps. From what I've seen, straps are generally really small. They don't look like they'd add any electrical benefit whatsoever, unless it's your only ground for something, in which case, you'd obviously need it.
