Scott,
The reticle in your picture is very similar to the Iron Sight, Inc., #1 style, what they used to call their "German #1" style, that I had installed on a couple of Denver Redfield 2-7x scopes. I find this reticle to very quick (obvious?) to the eye in heavy cover and under lower light conditions, but I don't know if it significantly quicker to the eye, or even if "quick to the eye" could be measured, than Leupold's heavy duplex.
