At 6'4" tall, I care more about legroom than width. Do the MCE rows (Row 9 or 10) on the A319 have noticeably more legroom than a standard economy seat? I ask because my current choice is to switch to a middle MCE seat from an economy aisle seat that currently has no one else next to me. (I guess I could also switch to a middle seat in Row 14 if that is a better seat.)
