Without getting into the whole making a better pilot argument, chances are you will never fly these old airplanes after your ppl. And if you never flown them before you will definitely not want to either. They are fun and that's what initial training should be. When I search for my ppl school they are almost all modernized but I still have an old aero-boero picture that's not around anymore from my Solo and first navigation. That's not around anymore but I'd love to fly it again for old times sake.
