I guess both have their place in the right situations.
No, they don't. The first scenario you describe (rotate speed) is not correct for that class of aeroplane. The second technique (take the weight off the nosewheel and it'l fly when ready) is correct.
We used to watch in horror visiting PPLs at Barton who had been trained (not at Barton) who would hammer down our bumpy 27, no attempt to relieve the poor old nose wheel which is not designed to take that sort of punishment, then at the magic speed, rotate. Those were aeroplane drivers, not aviators. Didn't they
feel it was pi55 poor aeroplane-wrecking technique?
