Senior year, I have room for one more AP

Next year, I'm taking AP French, AP Lit, and AP Calc AB (plus Physics Honors, Newspaper Honors, and African-American & Latino-American Studies Honors).

I'm taking all classes at my home school except for French, which is only offered at another school system facility (where they offer classes to all district students that normally wouldn't have enough people to be offered at regular high schools). However, since it's only offered during a "0 period" (which is an hour before normal high schools start), I would end up with an hour and a half travel period to go back to my home school.

Instead, I want to take one more AP for my senior year. I've narrowed it down to either Stats or Macroeconomics/Microeconomics (which are offered together as an equivalent to another class). Both are necessary for what I want to do in college. I don't necessarily want to take an "easy" AP, but I don't want one that will overwhelm me. Alternatively, I could take AP Physics 1 and forgo Physics Honors (which would screw up my schedule and probably force me to take both Stats and Macro/Micro anyway). However, I have a friend who is taking it who is sure she's going to fail (though she's doing great in AP Chem).

Which would be better to take as an AP (as opposed to college)? I've heard conflicting things about the difficulty of Macro and Micro, but I don't really want to take Stats just because it's easy.
