I have decided that I need a back-to-school bag since I received a good GTA position for the coming semester. So, after I get a few checks under my belt I'll make a trip to LV. Currently I am trying to decide between the Damier Speedy 25 and the Mono Tikal PM. They are two completely different bags, so I need some help deciding (even though the purchase is a few months away). I already have a Mono Speedy 25 and an Epi Mandarin Speedy 25. I love the Speedy, but it might be nice to have a shoulder bag, too, which is why I am considering the Tikal PM. I have the Mono Batignolles Horizontal, but it's awfully large. I also have the Mono Pochette and Musette Salsa. I've wanted the Damier Speedy for a long time, and it would be nice to not worry about vachetta. But, it would be Speedy #3. The shoulder bag (Tikal) is appealing because it's hands-free, but then there's the vachetta problem, and I already have four other Mono bags. So, it might be nice to have Damier for variety. Whew! So what do you think? Thanks!
