If you use the rudder to correct the loc deviation you will lose two (possibly pretty) friends, the crew standing in the rear galley really won't appreciate it.
In 12500 hrs on 737 I have never seen anyone using rudder except de-crab to land in xwind, and single -engine
(fortunately so far only in sim
)
Think if you read the Boeing FCTM you will find this is the normal way to control the beast, leave the rudder alone, the yaw damper is taking care of it in normal ops.
