Is it wrong to buy the same bag?

I was kind of in the same shoe as you before. I got my mono speedy 25 in 2006, and shortly later, I wanted a speedy azur 30 or a damier 30 in 2007. I couldn't really decide and ended up getting a mini lin croissette speedy 30 in blue. I got this because it looks quite different than the mono or damier and it is LE. I say go with your gut instinct. Either way, you wouldn't go wrong with your choices. I am no help, huh? Sorry...
 
I have both the Damier 25 & 30 because I just LOVE Damier, but looking back I probably should have got the Mini Lin Speedy insteadof the the Damier 30...I'd say get a different Canvas Mini Lin or even Damier Azur? :smile:
 
If you really want it, then I say go for it! But if you want a little more Variety, take a look at the mini lin or a mono speedy 30! You should just check em out IRL to see what you like.
