Couple things to consider.

No matter how well you do in your FAIP tour, you go thru another selection process driven by the needs of the Air Force in 3 years. Saw a few guys at END that did well as FAIPs only to get the Dreaded AWACS. That C-17 or -10 may not be there in 3 years. However, no matter what you fly you will be doing something worthwhile, its what you make of it.

In three years no one knows what will happening nor where.

Some prior Faips would probably have a better idea what you face when you finally get operational. My personal opinion is that T-6 IP would be a blast, but flying around the flag pole would get old. Plus the UPT formal show and relese crap is in full effect on that side.

T-1 IP is pretty dull (I was one), but it has its moments, and the CT XC cannot be beat. You also get to fly when the 38s an 37s are stop launch. And you have a great AC. And not so much of the UPT crap.
