HighFlyer...Navy guys dread going to the AF bases because there's so much negative gouge about them but I honestly have yet to hear someone say they flat out hated it. If anything I notice Vance/Moody guys saying they think the AF way is better. But really, you shouldn't worry about it, when I say that only a handful of people go there, I mean a HANDFUL. Maybe one Navy/MC guy out a an API class of thirty will go, maybe. As for where you'll end up: out of your hands. Ask for CC or WF and you'll probably get it, very few people go to the AF but they do have to send X number of guys. In fact, a lot of people WANT to go to Vance or Moody for different reasons and they're usually the ones to volunteer for it. Whenever none of them are around people get picked, and usually they're the ones with hours which you're asked to document on your student info sheet when you get to API.
As for your flight time, you may not have a lot compared to the guys down at your local airfield, but as for your fellow SNA's you'll probably find that you have more than all but a few. Most have none. Some have PPL's or maybe twenty something hours (like me) but the guys with the mountains of hours are usually the Embry-Riddle grads or the guy whose Dad owns a plane. Not a whole lot of them around. It is enough to get you out of IFS though, I think if you have 40 or more hours you're DQ'd. Pretty much everyone goes nowadays and I'm hearing mixed opinions on wether it helped or hurt. I can't see how it'd hurt, but I never did it.
Again, don't worry about where you go, really. Flexibility is a necessity because odds are you won't like some of the assignments you get anyway, and this ones only for a few months. I remember a friend who was hell bent on CC because he hated P-cola, heard horror stories about WF and believed CC was his best shot at getting PCS orders to K-rock. I Ran into him in the academic building at WF the other day wearing an HT patch. He thanked God he was back in P-cola, hated every minute of CC, and after 6 mnths of flying (never flew before) he was begging for Helos. You never know what will happen (or wether or not you'll like it when it does) so just do your best and Semper Gumby.
