I have both the City and the Purse and I like them both equally. However, they really are two different bags. If you're looking for a satchel I suggest the City. If you want a true shoulder bag I suggest the Purse. IMO the Purse is the most feminine style of all the motorcycle bags. That is why I decided to get one in pale rose. Either bag is a winner. I think you should get a Purse since you already have a City. You won't be disappointed.
I looooooooooove Sea's pics but I do want to point out that (as she has said before) her handles have stretched out--plus she is tiny! The handles on my Purse are not *nearly* that much longer than on my Cities. The Purse is definitely a bit more comfy on the shoulder but it's still snug for my taste (note: I am NOT tiny!). I'll try to post pics one of these days.
