I use a 3-D insert on top of a bale target, backed by another large bale target. Yesterday morning I decided to hang a tennis ball in front of the kill zone. I ruined that tennis ball with 6 arrows without stacking my arrows ie robinhooding them.
On another forum board ie The Green Screen, we do what is called First Shot Friday (FSF) meaning the first arrow for the day. You get 1 arrow, at a single small target for the event.
It hones your skill.
This weeks event, a grape suspended from 12" of string, to be shot from just 12 yards. Last weeks event was a foam plate with a 1" circle cut in the center placed at 12" out from the target bale at 20 yards. The winner would be the closest to the hole in the center. I shot it, I got it, but remeasured my yardage and found that I was just at 19 yards and a few inches so I DQ'd myself. I could have said that I was at 20 yards, but its a game of honesty.
Very fun to do.
