Chuck, they don't do it that way because their instructor teaches them to three point....
And the instructor does that because thats how he/she was taught
And most instructors can't afford to hire a taildragger and wring it out properly and find out for themselves because instructing is what they are doing while they try to get hired by an airline, rather than a career.
Times I am very happy to have learned to fly a Cub at Lasham, pulling gliders in to the sky. Minimum of six tows an hour, land where there is a vacant bit of airfield not too far from the next glider. Teaches landings and eyes out on stalks. Doesn't do wonders for navigation skills or pratting around on the radio.
No offence intended to career instructors. I was taught by one, and am trying to repay forward what he gave me.
