Got a link to that birdman write up?
The one benefit of grounding to the hood ground strap or to the engine bay, rather than the latch, is while it may not seem like you'd need the light for anything with the hood open, it's actually an EXCELLENT engine bay light at night. With the 30" on with the hood open, enough reflects off the grille that it lights up the whole engine bay perfectly.
That LED cover is only for the small ones right? No luck for one for a 30" or 40" bar?
On another note, I got my 40" Blackhawk in today. First impression I was PISSED! The box was IDENTICAL to the 30" one I got from ebay. The light looked identical, the wiring looked identical, but the price was over double at $550 shipped instead of about $225. But after I went out to my truck and compared it to the ebay 30", my anger subsided lol. The heat sync fins on the 40" Blackhawk are textured to increase surface area and cooling, the ebay one is smooth. The Blackhawk one has hardware on the front casing, the ebay one looks like it's more snapped together or something. The Blackhawk one has beefier wire insulation, the ebay one had more of a hollow insulation around the pair of wires. And looking into the LEDs, the Blackhawk one has square chips, the ebay one has round dots, so at least I know the blackhawk isn't just a re-shipped ebay one, it is better quality. And I know the 40" has 33% more light capability being 33% bigger than a 30", but it really did blow the 30" out of the water in comparison. The 30" made a HUGE difference over the headlights, but man oh man the 40" just takes it over the top daylight lol. Some of that may be beam pattern though, the 30" illuminates more area up close, the 40" illuminates more area far away. They both serve a distinct purpose which is good, it's not just redundant light.
All that said, I'd still buy another ebay 30" in a heartbeat for the price, and if I had known about them before I ordered my 40" Blackhawk, I would have bought the 40" ebay one too. I may actually buy an ebay 20" one to mount on my trailer for backing up.
