Murray,
I don't believe you've understood the fundamental point that you do not choose what you fly in the RAF. You do not have the option to leave if the RAF doesn't give you the aeroplane you want.
You are still coming over as someone who wants to use the RAF as a stepping stone to airline life. There's nothing wrong with planning what you might want to do in 10 or 15 years' time, but remember that the RAF will demand 100% of your attention and commitment while you are with them.
