I am at Vance but just for advanced E-6 (did primary in Corpus). Talking to a few of the Navy/MC studs here, I am getting a neutral to very negative opinion of the system here. I've gotten a good look at the 37 upclose, and it looks like it was built (on the inside) by Fred Flinstone and Barney Rubble: no TACAN, no VHF radio, no GPS, no NACWS or TCAS, but it does have ILS. I can't speak to the difficulty level, but my fellow AF T-1 classmates all felt miserable during 37 training.
Apparently there is some sort of rumor going around that if you come here you will have a better chance of getting jets, but word I have gotten both here and on this site as well as back during primary is that that rumor simply isin't true (infact, I've heard that the jet instructors at Meridian and Kingsville don't like (overall) the studs who come from Vance b/c they don't know the Navy's way of doing things (big boy method, vice babysitting method here) and they fall behind quickly).
If you come here, AF will give you a quick in-process medical check if you already have an up-chit that is still good, nothing to worry about on that end.
