Let me say that I absolutely love the Spy! If you really like it I'd get two! (Can you tell I'm not a paddington fan?) But, 1 of each would be the best of both worlds. All three would be the best, but if you're like me (broke) it may be hard to accomodate, especially since a each spy is going to be over $2K
If you don't really love the paddy then don't get it. I think it's better that you have 2 bags that you love, even if they are the same style, then to have 1 bag you love and one bag you think is ok. Especially when they cost $2000 each.
