I am new here too and everyone is very friendly. I would say go for the EXP, with VIPOW. Just love those things. Also, don't forget no miles from transatlantic on BA unless AA codeshare. I am sure you knew that if you were AA PLT but just wanted to make sure. Got screwed there when I was just starting out on mileage runs.

And you can upgrade anyfare except group and some crazy discounted fair tickets (resold) no one really ever sees.
