Thanks for all the comments! I went for a flight in the Tecnam on Friday, it seems like a nice aircraft (although several things were not working). I am not entirely sure that I like the school that much though, it seems slightly less professional than the other one. So I think I might try the Cherokee too and see how that is.
On a side note, if I complete some exams with one school, then change to a different school would I have to redo those exams? Or can they be transferred over?
