christmas tree/arrow head middle.. 1,2,3 are girls, 2 and 3 in the lanes to block any easy throw in the middle
while stopping the lanes, 2 and 3 needs to react quickly when the swing to the side is about to happen.. 2 will go on force, 1 will go on hard man to deny any swings on the immediate handler, 3 will stay in the lane and deny any cross field swings, 4 will be nearer into the 3 girls as handlers will tend to strike past the girls, you need to stop that and at the same time leaking NOTHING pass you. 6 will move in closer than normal in order to help 4 and 5 will move slightly towards the center if comfortable to help 6.. 7 will move according to offensive players
swing goes back to the middle and the zone reforms back to step #1, xmas tree/arrow head.. 7 moves back to middle
when a short swing happens and still in the middle 75% of the field, 2 and 3 does not go on the force, their job is to stop any pass thru or elevated swing from handlers.. 1 will continue forcing.. 6 will drop slightly because of the disc nearer to his side and 5 will centralize for any throws past 4 or overheads.
swing to sideline, 3 will put on the force.. it will be a mirror image of step #2 (trap), same rule applies for no down the line on the force. short deeps will shift accordingly to where offence and disc are.
