well, Ive been instructing for some years, and have taught in all the usual suspects. After thousands of hours, i have concluded (in my opinion) that there is only one true trainer, the Cessna 152.
They are easy on da gas, sturdy and reliable, a great responsive little trainer,they lead easily into the bigger and faster cessna models.
As for the Traumahawk, yes, they are a good trainer, but I never feel secure in them, just try stalling one, and watch(and listen) to the tail feathers.
Thats not natural! They also have a finite life wing spar. There are not many left now.........
I did happen to learn in Cessnas, back in da early 70's (150's then) but have done over 1,500 hrs in Pipers, but 'came home' to the Cessna family.
Gotta say, i like high wings (ever seen a bird with low wings???-the feathered type I mean) The old Traumhawks are handy as tie downs for cessnas, just park one under each wing. (sorry James, if you read this!!
)
Thats my opinion for whats its worth, from one who sits in the right hand seat.
Cheers.
