Everybody's eyes are different I guess. For me, a really bright sight pin blacks out everything behind it, and that sux. The brightest I've found that still lets me see what's on the other side is my oldArchers Choice Grizzly.But it's not a verticalpin sight.

The very best low light sight, actually best for all light conditions,is none at all. When you learn to shoot that way, barebow can't be beat for hunting.
