i voted for the damier speedy because it sounds more suited to your needs, AND it is a GORGEOUS classic bag. I have the damier speedy 25 and its my all time favorite bag, even though its not the newest or most expensive. I just love the look of it when it is being worn, i love seeing it on other people when i go out.
Secondly id vote for the sunset blvd, it is a gorgeous bag and the credit card slots n stuff make it more versatile. I have heard that perle can have a tendency to discolour so you might want to be carefull with that.
