The wisest thing I've done so far is, "Bid where you want to live, then the a/c you don't mind flying". If you're on 1st year pay, it doesn't matter if it's 7ER or MD, it all pays the same anyway. Once you're in the base you can commute, then your QOL improves significantly, and then you can worry about if it's the maddog or the 73 or the 75/76.

Unless you have the SJS, then it's another story
