I am talking about a very specific situation: Hunting for deer at ranges less than 150 yds, in poor light, and moderate cover, from a fixed position.
Sorry I contributed to thread drift.
I have a 2X Leupold scope on a .22 pistol for shooting 25 yard matches in a poorly-lit range. I find that a 2X scope, with a regular black reticle, works EXTREMELY well to help my eyes see the target in low light. With both eyes open, the 2X magnification is not enough to be distracting. Seeing the standard crosshair doesn't seem to be a real problem, even on a black background.
An illuminated reticle might help, or it might get in the way of your seeing much in low light. A little dot in the middle of the crosshairs, or something like the ACOG, could help you see the reticle. Any more, and I think you might see a lot of reticle and not much else.
Have you considered an IER ("scout") scope?
What I like about the 2X pistol scope is that I can really use both eyes -- a lot better than I can with any scope that's close to my right eye, including a red dot.
