Ho-stack setup: 4 and 5 active cutters
5 gets the disc on an under cut
6 fills in as the new active cutter since the disc moved
One of the old handlers want to fill in as a cutter to replace 5 as far away from the active cutters as possible, 3 is closest to the far sideline so 3 fills in as a cutter.
4 and 6 are active cutters
