My 2 pence.....
Remember, at 50ft, the bus will push it's nose down by 2 degrees. What I tend to do is, depending on wt & config - on appr keep a/c attitude at approx 2.5deg nose up. At 50ft, pitch upto 5 degrees and hold that attitude. Generally gives a good, stable transition to flare without too much float.
Secondly, where you look is where you land in the 320.
Good luck & happy landings
