I think I remember posting this a while back somewhere but for what it's worth...whatever you get you will love it. I have dudes in my squadron who wanted F's and now they love E's, I have friends who wanted E's and ended up in F's, they now love the WSO. My C buds think the Charlie is where it's at (they don't have to tank), they don't care that they're bingo on the ball half the time. You have a little bit of a choice in the matter, not much, but since you have a little bit, make a guess of what you think you would enjoy most. Trust me, you will love what ever you end up in. Also, it's 3 years, chances are you'll fly another airframe your next tour.
