I've flown a 150 backwards when I was getting my license with an instructor. It really isn't hard at all on the plane. You wait until upper winds are higher than usual, and go into slow flight, and you can have the plane go slow enough to have the wind push you backwards. At least this is what I remember from l977.
I learned to fly in a lease-back plane that my instructor owned. That would make some sense as he was in it flying his own plane with his particular student.
It was mentioned before, but if leasebacks are so good, why don't more instructors do it, or more airport personnel? Just some thoughts.
