I know exactly of what you speak. I have a Russian Gen 1 nite vision scope that is a night mare. I also have several of the Vari X 11 Leupolds. I love them, but I put them on guns that I set and never change. For my long range guns I like the VLR scopes. When you set the elevation for every shot you have to know how much the elevation is going to change with every click.
