Keep the aircraft straight with rudder initially, then lock your rudder
noip's absolutely right.
Push required rudder in, then lock it.
Pitch when/as required.
Do not rush the rotation, you'll need a slightly firmer pull at top end of the rotation but if you nail the engine out target pitch attitude using the right rotation rate you'll find V2 will take care of itself.
When clear of the ground use the
yoke to control heading.
Obvious point: Make sure you've got the raw heading as well as the pitch in your scan by frequently scanning down to the PFD compass arc... the Flight Director can be very misleading at this stage.
Don't rush to "unlock" the rudders when airborne, if your inputs are roughly right she'll fly OK, so don't correct any crossed controls until the gear is selected up.
