Start in standard horizontal stack 20 yards away from the disc, but with the left most cutter (B1) a bit closer.
B1 sweeps across the field. while B2, B3, and B4 shift left into the space B1 has vacated.
After B1 has caught the disc, we want our cutters to be free to make the decisions they think are best. The goal is that B2, B3, and B4 have move far enough left that they are left of B1. An easy decision tree would be B4 cutting break and B3 cutting deep.
RESET
Another decision could be B3 and B4 making in cuts to both the force and break side. While B2 cuts deep.
RESET
We can also bounce to handler B7 and have B4 cut deep
