2. Absolutely true - the AF is going to teach you their way to fly.
With that said - aerodynamics and instrument approaches are not really different based on the plane, it just is going to happen faster and with more stress. For many it is just the fact that getting "all those ratings" is a ton of money that the AF is going to be giving you when you get picked up for the program.
If you love to fly and have the cash - go for it. If not, study hard when you get there, because it ain't no joke!!
