Hello, I noticed some differences between the A321 with IAE engines and CFM engines. E.g.: With the CFM is the approach speed 145 knots and the nose is 2 degrees up. On the A321 with IAE engines the nose is with the same approach speed, fuel, Pax and load 6 degrees up.  Are there the same differences between these two engines types in real? On the YouTube videos form Lufthansa A321 they had also 2-3 degrees nose up, but not 6!    Do i missed something or is the approach
