Thanks for the advice guys.
FFF, spending the time "flying for fun" is tempting and I like the idea of getting some ratings on the way eg multi and complex and tail-dragger. I have the night one already - I did that Las Vegas night approach as part of it - truly specatular and I liked the ATC instructions too - "make your left turn abeam the Stratosphere tower and aim for it". Not sure the height of summer is the best time to visit Arizona though!
I'm still keen on the FAA/IR though, even if I only don't get it all done this trip. So thanks for the info and the links.
Got the new job offer through today. Time to go and resign
