Certain example embodiments of this invention relate to vacuum insulated glass units. The shield distributes the force of loading a spear gun over a body area such as a chest area or the thigh area of a person’s leg, greater than the butt end of the spear gun. The additional second set of pieces and some rule changes enhances the game. The bridge circuit forwards address and data phases from one module to another module of the plurality of modules; the plurality of modules only interface with the bridge circuit. As a result, the nozzle is operable for discharging the flow of air rearwardly over the finger without obstructing plant material flow thereover, the air flow being sufficient to blow at least a substantial amount of loose grain and other plant material located forwardly of the front edge of a header floor of the machine, onto the floor for collection by a conveyor of the header for processing. Other responding parties may be matched with other agents having the same agent profile or matched with second-best compatible agents.
