After a lot of research, I pulled the trigger on GTR for both high and low beams. The lows needed no adjusting and have a sharp cut-off. They might have slightly less throw due to being in a halogen projector, but the much higher light output is so much better. I have an eye condition called EBMD and it's made driving at night annoying if I'm facing oncoming traffic. The brighter headlights really help with this. The old halogens were washed out by oncoming glare, at least to me. There is a good cut-off and I have not been flashed once. The H11 GTR Ultra 2's DO FIT in the housing with no adaptations, cutting, or grinding.
I liken the high-beams to turning on the sun, making a dark country road almost daylight bright. I bought the PWM module, so there is no flicker. The DRL is "dimmer" than the high beam, but not by a lot, so I don't use them. However, I have tested them on rainy days and have not been flashed, so maybe it's my eyes.
I'm sorry, but I don't have before and after shots. I don't live near a place dark enough for that to be practical.
