I have one scope with the heavy duplex and don't really care for the reticle. A #4 or post and duplex is a better choice for a low light reticle. A 2.5x8 VX3 also wouldn't be my choice for a low light scope, I've got a couple and find them to be lacking in low light. I don't know why, but the 1.75x6 and 3.5x10's seem to be brighter.
Most Europeans who have experience on such matters would consider any Leupold scope "lacking" in low light conditions. Personally unless I'm shopping for lightest scope, dangerous game scope, or target scope I don't look at their products.
