12 bolt for M6, 9 inch for A4?
I've seen several threads mention 12 bolts for M6 and 9 inch rears for A4's as a rule of thumb. Any reasoning or explanation on why this would be?

You have it backwards...
a Moser 12 bolt will still get case deflection behind a 6 speed and cause the 12 bolt to whine.
a 9" is more power robbing then a 12 bolt and is better behind the 6 speed due to the 6 speed much more harsh on the power and torque transfer through the drive line.
The A4 would benefit from a 12 bolt more because the slightly less weight and drivetrain loss the 12 bolt has and is not as hard on the 12 bolt.
