Moonge if I had to make a choice I'd go with the spot hogg. I've got two copper john's and they are the older models. The design didn't make the vertical adjustment easy to use. Also adjusting the pins is a bit painful because you have to eyeball the set up and then hope when you tighten it down that it didn't slide up or down on you. The spot hogg has a more precise pin adjustment. Finally the holes that are in the copper john appear to make the sight resonate noise when the bow is shot. If I had to do it over on the spot hogg sight I probably wouldn't get the hunter version. I think you can get the same end product in the right-on version.
