1. A latch coupling, comprising:
a housing having an outside diameter (OD) and an inside diameter (ID);
a plurality of axial alignment slots located along the inside diameter (ID) of the housing, wherein a width (WAS) of each of the plurality of axial alignment slots is within 10% of each other;
an uphole radial extending latch collet selector profile located along the inside diameter (ID) of the housing uphole of the plurality of axial alignment slots; and
a downhole radial extending latch collet selector profile located along the inside diameter (ID) of the housing downhole of the plurality of axial alignment slots.
