It seems as though you've made your mind up already and, I have to say, that I agree with your sentiment that this is the last chance and there's nothing worse in the world than the words "if only".
I clearly enjoyed much of my time as, ten years later, I'm still here trying to sneak a look at what's going on in the world I left. So, if you've made your mind up to go for it, even after all of the above comments, then you'll never work with a finer bunch of people and you'll probably never be prouder (at work anyway) than when they stick that brevet on your chest.
