Hi there
I can't advise in relation to FTC directly. There has been much written on this forum in so far as they were meant to have been given a new lease of life under new owners (Alpine Aviation) but the last I heard was that had fallen through.
Best to check the exact position with the UK CAA and find out exactly what they are currently approved to do woth respect to the JARs.
I'm not sure exactly what training you still need to do. I'm supposing that you know that if you hold an ICAO CPL then the only training you are required to do for the JAR CPL flight test is at the discretion of a UK based FTO to obtain the pre-entry 170A form, and not the mandatory 25 hour Modular course.
There's plenty of decent schools in SA but none offer the full JAR course as yet. If you search these forums the feedback on FTC is not too good.
Good Luck what ever you decide.
