Your gonna be very disappointed, there are frosty spiked CFIs at every flight school in America. You'll see when you actually step foot in the business. They are everywhere, in fact they will also be students who will eventually be instructing. So does that mean that they are not professional because they once had frosty spiked hair? Hardly.
I dont get it, you have never been in an ATP establishment, yet you present yourself as someone who knows everything already. I would like to know where you get your expertise from? I am not trying to start a ****ing contest with you, I am just curious.
