Stick to Boeing!
Unless You want flapload relief on a regular basis.
The 737 is a glider on a CDA approach as I assume everyone are doing now..
The deceleration to speed selected is so gentle and slow that there is plenty of time to reverse the selection up to a higher speed if there is an issue.
I would strongly advise against outsmarting Boeing.
An operator I know for a long time started off with massively modifying the new 737 -800 operation to fit the old 737- 200 SOP.
It almost ended in tears many times until it sunk in that Boeing actually knew what they were doing.
It did not help that the local CAA had no clue, and resisted a few changes.
Re-inventing the wheel or the picture I like : Re-inventing the Dynomite, Nobel`s brother tried that . And promptly blew himself up.
Happy Landings
