The point I'm trying to make is that the OP asked for advice, to be told that aircraft bite fools is not necessary.
That's appreciated, though I have no real objection to being reminded once in a while.
It's an interesting observation that when I shortly fly an unfamiliar aircraft solo for the first time, prior experience on similar types is denied to me because of legislation presumably intended to improve safety...
I suppose there's also the safety of the instructor to take into consideration - perhaps it's unfair to ask an instructor to teach on an uncertified aircraft, yet if I owned a 2-seater I could legally be instructed on it - as I understand the situation.
If I were an instructor I think I'd rather teach people on an aircraft I owned than one I was less familiar with and that may not have been maintained to my standards. Whether or not I'd want to instruct on a permit aircraft belonging to a school is another matter again.
