I don't think the Marine experience at IFS has changed. I know that the Navy guys doing IFS at Skywarrior in Pcola are having a tough time. AFAIK the Marines who do IFS in this area do it at AMS in Milton/Peter Prince.
Skywarrior has a completely different atmosphere. I've had one experience with them and will never give them any of my money in the future because of it.
They're sending Marines to SkyWarrior now, as well. I've heard nothing but horror stories from that place, and that's coming from both the blue and green sides of the house; it's ending careers almost as quickly as Tailhook (I kid, I kid).
IFS isn't the lazy day experience that some earlier guys remember. They moved all the training down to the Pensacola area for both Navy and Marine Corps officers. Everything is standardized in ground school via 5 hour workdays in the computer lab, along with proctored tests. No take homes, no bonus notes, no book; just the standard computer supplement (which does help a lot). It is a "screening process" in every sense of the word, and kids are being dropped from almost every class.
I know I definitely wish I'd had my PPL prior to reporting, but hindsight is 20/20. If you've got the time and money to do it, more power to you. If not, it isn't the end of the world. Most people make it through IFS, so it's not a death knell or anything. There will be parts of the training pipeline a lot harder.
