UnitedSkies,
If you're in CW, go for the upper deck. I like 62A/62k more than any other seats. They have aisle access and windows. What more can you ask?
Just a note -- you can't store anything in front of your seat in CW, as the footstool takes up the room. You'll need to put everything in the overhead bin. I will say, I've never found it to be a problem. But then, I usually only carry a back pack into the plane.
