Some shooters like multi reticle scopes, it just takes more shooting and learning to use them. They can be very good with them. I've shot them before, but never cared for them.

I'm a retired Ergonomist, or Human Factors Engineering. What happens with many, not all, is what's called "Task Saturation". The human is given more choices, of which he must be sure of in a very quick amount of time. Range finders should be use in all cases.
The military trains pilots exclusively to handle Task Saturation. Imagine flying an F-16, with its multitude of controls, switches and visual requirements, all while being shot at. Those men and women are good!
