In our horizontal set typically the two middle cutters are primary looks
If you're a center cutter, coordinate with the other one to determine who's initiating. Can be verbal or nonverbal
In this example, 5 initiates under and 4 cuts deep
clear to the break side if not open, if cutting deep, come back under
5 can either clear deep or to the side - 6 becomes active
if disc gets to 4, 6 can either cut deep
or cut under
5 can continue up the outside lane as a deep threat
