Will not care where you have done your ATPL theory.
If you can do your ATPL theory for less money and get the same quality of training then you should do just that.
As long as I've been in these forums all I've heard about Bristol, AFT, Naples, Oxford is all good.
Not saying that IFTA (if that's it's name) is worse or better, merely that these schools seem to have a good name.
For your own benefit I suggest using the SEARCH option on this forum and type in school names and see what is said about them.
Hope you find what you want and gl on your career.
