Sorry I wasn't clear enough. What I mean is that your pitch attitudes to fly are fairly similar between the aircraft in the various flight phases. So your approach/flare pitch attitudes are similar and should be nowhere near the tailstrike pitch limit in any of the types.
Tailstrike pitch attitude is indeed different between the various A320 series members. For example we call 'pitch pitch' during the flare on the A321 at 7.5 degrees and at 10 degrees on the A320 to alert the other pilot to lower the nose.
