Two chasers work in tandem to maintain a middle force on the primary handlers. Chasers mark the thrower and force side dump tightly so that there is no easy reset. Red 3 protects the inside lane and the up the line cut from Blue-1. Red-4 covers the crashers. Red-5 protects the open side. Red 6 and 7 split the deep space.
As the disc moves, the cup and the wall move as a unit. If the disc gets to blue-3, Red-2 becomes the mark and keeps the flick force. Red-1 sags into the lane to become part of the trap cup with Red-4 and Red-5. Red-3 covers the short over the top throw in the break side. Red-1 must be ready to recover if Blue-3 breaks the mark to Blue-2.
If the disc gets back to Blue-2, then Red-1 recovers as quickly as possible back to Blue-2 and establishes the flick mark. Red-2 stays where they are. Red-3, -4-, and -5 shift over so that Red-3 and -5 are covering the lanes. Red-3 is also ready to cover the up-the-line cut from Blue-1.
