Since you have two decks with a ball tray I suggest setting up to wash on the screen. Don't know your max oversize but maybe you could combine the oversize and undersize and find a market for it also. A warning: the screen cloth will wear fast where the sprays hit them so set up the spray bars so they can be moved back and forth to maximize screen cloth life. Play around with spray pressure to arrive at a happy medium between screen cloth life and product cleaning. Mike
