Great write up and comparison! I've seen Luis's work also on a E60 (5series) and it was also flawless too.
I love my Orion V2's. (Which is what he uses)
Thanks for sharing!
P.S. Here is a comparison on my friends Reiger Kitted E60 (HID Angels) compared to my stock E60 (Orion V2 Angels) (I know the car is hideous now, but had to sell everything for more important things. Those were my M5 mirrors!
Orion V2's are on the Left and HID Angel eyes are on the Right.
Here is the pic HDR style.
