I did my taildragger add on in a Cub and a Stearman PT17. Until them I had been bumbling happily around the skies in either a C172 or PA28. I can honestly say working on my taildragger endorsement made me realise just how lazy I'd become when it came to flying the aircraft all the way to parking.
I would encourage any pilot to do a taildragger course even if they don't intend to own one.
And besides anything else they are bloomin good fun !
