IO you really have a chip on your shoulder about FI's. Where did you learn initially that was so awful?
The reality is though that "traditional" methods have been refined through the teaching of tens of thousands of students over the last 90 odd years. They may not work for everyone, but look at the average school or University and see how much allowance they make for personal learning styles... Not much.
I hear alot of slagging, but no constructive points. If FI's are so bad, then go and get a rating and start teaching. Initially, you'll go straight to the mnemonics and basic patterns when you realise how hard it is to teach someone with no ounce of mechanical skill or sometimes intelligence how to actually fly an a/c and do eveything else. It's only after time that you'll learn how to teach in different ways or to adjust what you are doing for a certain person.
It is not an easy job, but none of us ever complain about it, infact the only bitching you'll hear from FI's is about pay, conditions or how stupid some of the students/PPL's have been. Yes, bouncing around the circuit for the hundreth time that week can get a bit wearing but that's a minor gripe really.
There are certain things in flying that can be of a personal nature, crosswind landing techniques for example, BUT there are certain things that are laid down in stone and there is no room for "interpretation" in them at all.
