X-Men Perfect

Okay, some of you have been debating my opinions of X-Men, and I am cool with that. It got me to thinking, though... What would you consider to be a picture perfect team of X-Men? Doesn't matter if members are living or dead, and if you want to name which character version and costume you'd use, please do.

I'd answer myself, but I haven't thought about it...

Oh, and please limit your choices to seven characters.
