Do many of you set the OOS without the setters?
Unless one has the hands the size and strength of the Incredible Hulk, one nearly has to use setters. The setters are also useful in a softly dry firing the OOS checking for a root, stone, mulch or debris (along the trap legs' pathway) in the trap set. Holding on to the setters while tripping the trap will accomplish this. Oversize setting tools help in this regard. I'd probably only want shake hands once with anyone setting this trap without setters!
