GullWing,
As an instructor who worked (at a previous job) with a couple of instructors whose styles might be described as less-than-perfect, I have a few comments.
First of all, appreciate that we are all different - and by that, I mean both instructors and students. You clearly did not get on well with this instructor, but that doesn't mean is not an excellent instructor, and you might well find that other students of his get on perfectly well with him.
That aside, you should definitely have a quiet, non-confrontational word with the school's manager or CFI. If this is a genuine problem with this particular instructor, and not just a personality clash between the two of you, you will most likely find that the CFI is already aware of it, but he will definitely welcome your input.
I can think of one particular ex-colleague of mine whose style put a lot of students on edge. Once this had been brought to the attention of the manager, he sat down with a number of students who had all refused to fly with the instructor, and heard their side of the story. Then, he sat down with the instructor and presented him with examples of what his students had said. The instructor's attitude changed overnight, and everyone came out on top - but only because the students were open and honest about the problems.
As for your regular instructor, of course you should be honest if he asks how the lesson went, but don't expect anything to be done as a result of this. He certainly won't want to get involved in "office politics" by bad-mouthing his colleague to his boss on your behalf. I'm afraid you'll have to do that yourself.
Good luck with the rest of your training!
FFF
