At this point rudder input into the wind and very slight aileron into the wind is used to maintain centerline up to and after rotation and to crab for climb out. YMMV
And you describe quite the opposite of what's discussed here. What 737 series are you referring to in your statement?
@all: The new effect is related to high bypass engines and them pushing a considerable higher mass of air than former models?
