Ok Rainbow. I think we are on the same page more or less.

The technique I describe works very well for me. The whole process of rotation and initial climb always feels under control and therefore I have no inclination to rushing the rotation and risking a tailscrape.

Also you might be right about there being some crosswind not being accounted for by the crossed controls once airbourne, however the aircraft type I fly has a map referenced to track and it does not ever indicate any drift more than a degree or so.

Also to clarify, I begin to reduce rudder input as soon as I am finished with the rotation and am at the correct attitude for initial climb (15 - 18 degrees nose up). This would be at about 100 ft AGL. The time it takes me to then centre the rudder pedals is about 3 - 5 seconds depending on how much they're displaced. So even if I was drifting a degree or so, it would only be for a matter of seconds.

Of course as you climb, the wind tends to strengthen and change direction as well. Once the rudder is back to centre I would certainly be using aileron to adjust the heading in an attempt to maintain runway track.
