I'm a righty and right-eye dominant most of the time, so, given that I take a pre-mount swing toward the house and then out to the holdpoint--with emphasis on finding the old human backsight in alignment with the rib both vertically and horizontally--and then lower the butt below shoulder it's at least likely that I look up the rib with the right and scout for orange with the left. No one taught me this "out in front baton pass" method. I knew guys broke targets before the stake and I didn't. I could also see their "insertion" point and the short stroke of the muzzle and one day I stopped chasing and did it. After a while, things did slow down a bit and I can now more or less analyze what I do--I hope! How do you guys shoot 8? Lot of shooters deal with it (even if pre-mounted) as an overhead. I shoot both 8s pre-mounted but hold outside the house about 2' and pretty much on what appears to be the path of the target, move on the sound of the trap and pull the trigger. This is a pure robot shot of no use whatsoever to a hunter but I seldom miss at 8 and break them well before overhead (even in blinding sun). I don't know if skeet still helps grouse hunters; in some ways I sort of doubt it. But I will say that on a sporting course, if you see target trajectories that look similar to skeet targets, you'll be conditioned to shoot them with skeet methods.
