Qavion:
You're quite right; on re-reading it I can understand your confusion.
What I was referring to was a situation that would cause problems in keeping it down the middle, e.g. single thrust reverser or severe cross wind. If there is a need for strong pedal input to keep it straight, it is likely that most of the braking (non-autobrakes size 11's) will come from that same side. This will be less effective than allowing the A/B's to do the job for you, evenly.
Bye.
