Welcome to the Wannabee forum of Pprune.
It is good to know that you have been doing some lengthy research and you will undoubtedly find a lot more information here.
However, the choice of an FTO is a very subjective thing. Some suit one person's way forward and others may not. Consequently I suggest that you should use the Search function to go throught the threads here, make your notes on each and then when you have a a list of a few that you really think would suit you GO and VISIT THEM. Take a trial flight and see what YOU think of the setup.
You are likely to be parting with a large sum of money so why take the anonymous view of a few here. There also the sciolists (see at bottom) who will be less than helpful by giving you wrong information.
Consequently I am closing the thread before the idiots start there usual baying! Let me know by PM if you need to re-open it.
