Having seen abysmal standards in the most basic skills of some people, I am inclined to believe that everyone should learn to fly on a tailwheel trainer to avoid bad habits that make for poor skills in any but the most benign kind of plane.
Yes, I was lucky that there was a place with Rollason Condors, which had a lovely narrow envelope that teaches you to keep on your toes. It's a pity that such places have disappeared alongside the oldfashioned stick-and-rudder instructors that were around in the seventies. Now you have a chance of being tought basic skills by an instructor who spent his entire flying career so far on (***) (very fault-forgiving) airplanes !!! In fact, I wrote an article in the Flight Safety Bulletin years ago voicing my concern about this fact and urging GASCo to look into the relationship between this and accident statistics.
There many more about now than when I learnt in the 80's. I did my PPL on taildraggers (DH82a and Supercubs) after flying gliders. The Cambridge Flying Group and Clacton Aero Club still exist, but many more offer ab-initio on taildraggers than did then.
