The impression I got from Ian Cheese when he stated "two providers for your commercial training" was that he meant training beyond ground school?
This therefore could mean an alliance like OFT/Cabair, MFC/Cabair, and other FTO's that combine with an overseas training provider for part of the CPL or IR?
There is a lot to be said for doing the IR in particular in the UK, purely because of the airspace structure and the familiarity you will have with it. The CPL is not so much of an issue - you will learn all the airspace structure you need to know with the IR.
