Glider, EFT are very good. They also charge way more then anyone else but thats a decision for you to make. I did my CPL there and they ironed out a lot of bad habits I had, and I got through in minimum time and in two and a half weeks and tested in under three.
I too am considering doing my FI rating. Rightly or wrongly there is a poor view taken of people who have done all their flight training in America, like myself. I have been told by a few school owners that they would not employ such a person. I also have little knowledge of some of the proceedures for flying in Europe, and I feel it would be irresponsible to teach students with so little knowledge myself. If I do my FI it will be in Britain, as that is where I will be instructing
That is my own opinion, I would be interested to hear what others think.
