There has been alot of real good advice given here titleist. I do all my bowhunting from a tree stand, therfore I practice from an elevated position with a 3d target. Either from the roof of my house or a ladder stand. Just like benhuntin, I too will only take a few practice shots each time. And I beleive my most important practice shot is my 1st shot. But, there are alot of variables that come into play when the moment of truth arrives. I've seen guys that can split hairs on a 3d target but completely miss a live buck standing 15 yards away.
