Re: 3D course and the traditional shooter ?
We have got compliments from trad shooters on our stake placement and shot set up. Lots of thought put in to it. I set up hunting situations and not interested any more on hearing arrows shatter in the rocks. Have to agree with "The Hermit" on scoring rings. If you shoot them, it's not as such good practice for hunting situations, other than having to focus on a point. Shoot as many 3-d as possible as there is nothing like it for practicing hunting shots - even if you have to shoot from your own spot (as long as it's safe).

Bowhunting is seeing how close you can get and never miss your mark."
