1. not rotating - "Get the nose wheel up early off the poor surface….. let the plane fly..." (yourself)
In effect raising the nose wheel is rotating I guess but not in the conventional sense. I would open the throttle, apply up elevator as required to lift the nose wheel, probably to the full extension of the oleo and wait. Ease off back pressure as required during acceleration to maintain this attitude. Lift off happens in a most pleasing manner
.
Also remember to be specific to cover every eventuality or otherwise acknowledge when the advocated technique is not applicable.
In the (land) singles I fly, this is the only technique I ever use anywhere ever. Not applicable for seaplanes!
A brilliant book on the subject and highly readable is "Take Offs and Landings" by Leighton Collins. I got my copy from the Kindle Store onto my Ipad.
