Well, I'll probably never get around to it but the ideal set up would be to show up at the range on a day when you are the only guy there and have the trap set so the target flies the same every time and use the tracker wads until you get that particular shot down correctly, then move on to a target at a different angle. Actually, if you could get a group of folks to want to do the same, maybe have five people, one at each station, with a coach or spotter behind each shooter, and have the clay fly the same five times, then on to the next station.
