Pull what - I don't believe it. However, I've been told many times that power off approaches are not a good idea because the steep angle makes the flare difficult to judge. Personally I consider that absolute rubbish, but there we go..
I'm very much in agreement with PilotDAR wrt training, and I think CJ driver has a point about 3 degree glide slopes - but I can't for the life of me see why you need to fly a 3 degree slope in a 172, nor, if you must, why you can't wind the rest of the flap out somewhat later on final.
As for long runways, one can adjust the aim/touchdown point to finish up somewhere near a turnoff. Probably another howling at offence (runway behind you being useless and all that)
